    Description / Table of Contents: On the Corrosion of Wine Bottle aps Made of Thinly Tinned Lead (Tinfoil Caps) and their TestingSeveral method have been developed for the testing of the thickness and porosity of the tin layers of the customary tinfoil caps. The tin layers of commercial wine bottles were found to be less than 0,001 mm and for a great part considerably porous.To test the resistance of the caps to corrosion, laboratory experiments and practical storage tests have been carried out with commercially capped bottles. Under certain conditions which might be met in practice the caps were corroded considerably, and in some cases they were deteriorated totally. The corrosion products are lead salts.
    Notes: Es wurden Verfahren für die Prüfung der Dicke und der Porigkeit der Zinnauflage auf den üblichen sogenannten “Stanniol” - Flaschenkapseln entwickelt. Kapseln von aus dem Handel bezogenen Weinflaschen waren fast stets unter 0,001 mm dick verzinnt und meist erheblich porig.Zur Prüfung der Korrosionsbeständigkeit der Kapseln wurden Laboratoriumsversuche mit Kapseln und praktische Lagerversuche mit handelsüblich verkapselten Flaschen ausgeführt. Unter gewissen Bedingungen, die in der Praxis durchaus vorkommen können, wurden die Kapseln unter Bildung von Bleisalzen erheblich korrodiert, in einigen Fällen sogar völlig zerfressen.

    Description / Table of Contents: The Vanal Process A new Way to Protection against CorrosionThe Paper contains a description of a new method to protect the surface of fireproof building-materials against untimely corrosion at high temperatures. The protective effect depends on surface tension. So this principle has been applied to protection against corrosion for the first time. Suitably arranged protective covers prevent any penetration of gases and slags. The technological and economical advantages of this process especially by application of silicon carbide are explained by means of practical examples.
    Notes: Es wird ein neues Verfahren beschrieben, durch das die Oberflächen feuerfester Baustoffe vor vorzeitiger Korrosion bei hohen Temperaturen geschützt werden. Die Wirkung beruht auf dem Gesetz der Oberflächenspannung, das hierfür erstmalig angewandt wird. Durch entsprechend ausgerichtete Schutzschichten wird das Eindringen von Gasen und Schlacken verhindert. An Hand von Beispielen as der Praxis wird der technische und wirtschaftliche Vorteil dieses Verfahrens besonders bei Siliciumcarbid erläutert.

    Description / Table of Contents: On te behavior of bras in diluted solutions of mineral acids and teir mixtures in presence as well as in asence of inhibitorsThe loss of weight of brass 40/60 in mineral acids and teir mixtures in presence resp. absence of inhibitors does not consist additively of the losses of weight caused by the not mixed acid solutions. The attack of acid mixtures does not depend on the activity of H-ions only but on the effecitivity of the anions also. In HCl - H3PO4 mixtures of constant acid concentration lower losses of weight were observed than in the pure acids of corresponding concentration. Inhibitors cause in some acids decreased, in others increased atacks. Mistures of inhibitors might show better or even worse effectivity than single inhibitors. Dezncking of brass will be prevented by application f inhibitors especially by those of high inhibitive effectivity.  -  It may be allowed to conclude from the dependance of the anion effectivity on the accelerating or inhibiting effect of the inhibitors at constant H+ activity tat the inhibitive effect does not so much depend on the mechanism H + H → H2 but on the more or less favorable conditions of the formation of protective covers.
    Notes: Die Gewichtsverluste von Messing Ms 60 in Mineralsäuren und deren Gemischen in Ab- bzw. Anwesenheit von Inhibitoren, setzen sich nicht additiv aus den Gewichtsverlusten in den Einzelsäuren zusammen. Bei den Säuregemischen hängt der Angriff nicht nur von der Aktivität der H-Ionen, sondern auch vom Anion ab. Im HCl-H3PO4-Gemische werden sogar bei gleicher Säurekonzentration niedrigere Gewichtsverluste als in den gleichstarken Einzelsäuren beobachtet. In manchen Säuren wirken Inhibitoren hemmend, in anderen jedoch sogar beschleunigend. Gemische von Inhibitoren können sowohl bessere, als auch schlechtere Wirkungen als jeder Inhibitor allein aufweisen. Die Entzinkung von Messing wurde durch Inhibitoren, namentlich bei höherer Hemmungswirkung, verhindert.  -  Aus der vom Anion abhängigen Beschleuniger- oder Hemmungswirkung der Inhibitoren bei gleich großer Wasserstoff-Aktivität wird geschlossen, daß die Inhibitorwirkung weniger vom Reaktionsmechanismus; H + H → H2 als vielmehr von den mehr oder weniger günstigen Bedingungen für eine Schutzschichtbildung abhängt.

    Description / Table of Contents: Sress corrosion in homogeneous alloys, its conditions and its mechanismAt first the kinds of alloys showing the optimum initial conditions for an investigation of stress corrosion are discussed. According to the author's opinion homogeneous, not supersaturated, binary mixed crystalls of very noble components will be suitable (e.g. CuAg, AgAu, etc.)The occurence of stress corrosions is dependent on the following conditions: 1. characteristic susceptibility of an alloy to stress corrosion. 2. chemical action of a corroding atent at least upon the less noble constituent of the alloy. 3. tensile stress. These problems have been made subjects of exhasutive investigations.The most important factor influencing the suceptibility of homogeneous mixed crystalls to stress corrosion cracking is the amount of the mixed crystall concentration. About this series of exhaustive experiments as well as of analogous experiments under the influence of mercury were carried out. The result is that the reactivity of the gret angle grain bundaries as well as of the glide planes will be increased considerably with increasing mixed crystall concentration and will reach its maximum at 50 atom percent. so a new “mixed crystall effect” was found which is the chief cause of the suceptibility of homogenous mixed crystalls to stress corrosion.Further reslts are that under the inluence of chemical agents the mixed crystall effect will only be noticeable if the attack is supported by an electochemical process. Investigations showed that during the attack on homogeneous mixed crystalls electrochemical processes might occur if the basic metal is less noble than the alloyed constituent. Tis explains the peculiar course of the susceptibility to stress corrosion in dependence of the mixed crystall concentration which does not correspond to the alteration of the reactivity.Finally exhaustive investigations on the effect of tensile stress were carried out. Tensile stress was found to be effective only if it causes local, plastic deformation. So a considerable increase of reactivity will take place in statu deformandi only. The increase depends on the concentration of mixed crystalls as well and will reacgh its maximum at 50 atom percent.Then the causes of the occurence of inter- resp. transcristalline cracking in cubic face centered mixed crystalls are discussed. From the obtained results a conception of the mechanism of the formation of inter- and transcristalline cracking is developed.
    Notes: Es wird zunächst die rage diskutiert, welche Art von Legierungen die günstigsten Ausgangsbedingungen für eine Erfassung der Ursachen der Spannungskorrosion aufweisen. Dies sind nach Ansicht des Verfassers homogene, nicht übersättigte binär Mischkristalle aus möglichst edlen Komponenten (z. B. CuAu, AgAu u. a.)Für das Auftreten von Spannungskorrosion müssen bekanntlich folgende Voraussetzungen erfüllt sein: 1. Spannungskorrosions-Empfindlichkeit der Legierung; 2. Einwirkung eines chemischen Agens, das wenigstens die unedlere Komponente der Legierung angreift; 3. Vorhandensein mechanischer Zugspannungen. Über diese 3 Punkte werden eingehende Untersuchungen angestellt.Als wichtigster Faktor, der die Spannungskorrosions-Empfindlichkeit homogener Mischkristalle beeinflußt, erweist sch die Höhe der Mischkristallkonzentration. Hierüber werden eingehende Untersuchungen durchgeführt, die durch analoge Untersuchungen unter Einwirkung von Quecksilber ergänzt werden. Diese führten zu der Erkenntnis, daß das Reaktionsvermögen der Großwinkel-Korngrenzen wie auch der Gleitbereiche mit zunehmender Mischkristallkonzentration ganz beträchtlich erhöht wird und bei 50 At-% ein Maximum erreicht. Damit wurde ein neuer „Mischkristall-Effekt“ erfaßt, der die Hauptursache für die Spannungskorrosionsempfindlichkeit homogener Mischkristalle darstellt.Ferner ergab sich, daß sich der „Mischkristall-Effekt“ bei Einwirkung chemischer Agentien im allgemeinen nur dann bemerkbar macht, wenn der Angriff durch einen elektrochemischen Prozeß unterstützt wird. Untersuchungen hierüber legten klar, daß auch bei homogenen Mischkristallen während des Abbaues derselben ein elektrochemischer Prozeß auftreten kann, allerdings nur dann, wenn das Basismetall unedler ist als die zulegierte Komponente. Damit erklärt sich der eigentümliche Verlauf der Spannungskorrosionsempfindlichkeit in Abhängigkeit von der Mischkristallkonzentration, der sich nicht mit der Änderung des Reaktionsvermögens deckt.Eingehende Untersuchungen wurden schließlich noch über die Wirkung der Zugspannungen ausgeführt. Wie sich ergab, sind sie nur dann wirksam, wenn sie ein örtliches plastisches Fließen hervorrufen. Es tritt demnach nur „in statu deformandi“ eine beträchtliche Reaktionssteigerung auf, die ebenfalls von der Mischkristallkonzentration abhängt und bei 50 At-% ihren Höchstwert erreicht.Es wird dann noch die Ursache für das Auftreten inter- bzw. transkristalliner Risse bei kubisch-flächenzentrierten Mischkristallen behandelt und abschließend eine aus den hier gewonnenen Ergebnissen resultierende Vorstellung über den Mechanismus der inter- und transkristallinen Rißbildung entwickelt.

    Description / Table of Contents: Electro chemical processes in stress corrosionElectro chemical investigations of simple model systems show that stress corrosion as occuring in several alloys may be explained by interaction of two effects. The narrow localisation of the corrosion process is caused by the mechanism of plastic deformation processes. Under plastic deformation the atoms on the lines of the slip planes or on slipping grain boundaries along the surface will be activated and dissolved favorably. By corrosion passivating covers are formed on the surface of all alloys suceptible to stress corrosion (Increasing concentration of the more noble constitutent or pasivation). Cracking of these covers under plastic deformation increases the localization of the corrosion process and causes the phenomena of the tension crack corrosion. The article shows in which way these processes could be read from anodic corrosion currents.
    Notes: Elektrochemische Untersuchungen an einem einfachen Modellsystem haben ergeben, daß die bei verschiedenen Metall-Legierungen auftretende Spannungskorrosion vor allem auf das Zusammenwirken zweier Effekte zurückgeführt werden kan. Die enge Lokalisierung des Korrosionsvorganges wird hervorgerufen durch den Mechanismus plastischer Verformungsvorgänge. Die Atome an Durchstoßungslinien der Gleitebenen oder abgleitenden Korngrenzen mti der Oberfläche werden bei plastischer Verformung aktiviert und gehen sehr bevorzugt in Lösung. Bei allen spannungskorrosionsempfindlichen Legierungen entstehen durch die Korrosion auf der Oberfläche korrosinshemmende Deckschichten. (Anreicherung eines edleren Legierungsbestandteils oder Passivierung). Das Aufreißen solcher Deckschichten bei der plastischen Verformung verstärkt die Lokalisierung des Korrosionsvorganges außerordentlich und führt zu dem Phänomen der Spannungs-Korrosion.In der Arbeit wird gezeigt, wie sich solche Vorgänge im anodischen Korrosionsstrom nachweisen lassen.

    Description / Table of Contents: The Resistance to Corrosion of Condensor Tubes Made of Copper AlloysThe resistance of condensor tubes made of copper alloys depends on the properties of the material used and the conditions of operation. Besides of the positive normal voltage of the copper alloys their property to form good protective covers is a important factor in directing their stability. The copper alloys mentioned in this paper are more resistent to corrosion than pure copper as they contain relatively resistent alloy constituents like nickel, tin or even aluminium which supports the formation of good covers. The most common form of corrosion are corrosive erosions, dezincification, deposit attack, season cracking and fatigue cracking. The degree of wear depends on the composition and the temperature of the steam, the cooling water, the way of operation and the construction of the condensor. The behavior of the cooling water upon the alloy is chiefly determined by the pH-value and its content of carbonate, chloride and oxygen. Most the difficulties are caused by soiled water especially when the condensor is first in operation. The material must be selected according to the different conditions of operation. For inland waters SoMs 71 (admirality's brass) and for sea waters SoMs 76 (aluminum brass) as well as Cu Ni 30 Fe (Copper-nickel-alloy) have proved to be qualified.
    Notes: Die Korrosionsbeständigkeit der Kondensatorrohre aus Kupferlegierungen hängt vom Werkstoff und den Betriebsbedingungen ab. Neben dem positiven Normalpotential der Kupferlegierungen ist besonders deren Eigenschaft zur Bildung einer guten Schutzschicht ein wichtiger, die Beständigkeit lenkender Faktor. Die hier benutzten Kupferlegierungen sind korrosionsbeständiger als Kupfer selbst, da sie relativ korrosionsbeständige Metalle wie Nickel oder Zinn enthalten oder Aluminium, das die Bildung einer guten Schutzschicht unterstützt. Die häufigsten Korrosionserscheinungsformen sind Korrosion-Erosion, Entzinkung, Angriff durch Ablagerung, Spannungskorrosion und Korrosionsermüdung. Die Betriebsbeanspruchung hängt von der Zusammensetzung und der Temperatur des Dampfes und Kühlwassers, der Betriebsweise und Konstruktion des Kondensators ab. Das Verhalten des Kühlwassers der Legierung gegenüber wird vorwiegend bestimmt vom pH-Wert, dem Carbonat-, Chlorid- und Sauerstoffgehalt. Die häufigsten Schwierigkeiten bereitet verunreinigtes Wasser. Besonders bei Inbetriebnahme ist darauf zu achten. Der Werkstoff ist den verschiedenen Betriebsbedingungen anzupassen. Als geeignete Legierungen haben sich erwiesen: SoMs 71 (Admiralitätsmessing) für Binnenwasser und SoMs 76 (Al-Messing) sowie CuNi 30 Fe (Kupfer-Nickel-Legierung) für Seewasser.

    Description / Table of Contents: Investigations on the Influence of Oxygen upon Iron SurfacesThe behavior of solid and pyrophorus iron surfaces upon commercial and purified nitrogen and their tendencies to oxidation was investigated. Stroing both the materials in pure nitrogen the gas does not influence the tendency to oxidation as demonstrated by special glowing experiments. The decrease of pyrophority of iron powder being stored in commercial nitrogen is explained by the presens of traces of oxygen in the protective gas which cause a slow but undisturbed formation of an oxide layer.
    Notes: Hinsichtlich ihres Verhaltens gegenüber technischen und gereinigten Stickstoff und ihrer anschließenden Oxydationsneigung untersucht wurden kompakte eisenoberflächen und pyrophore Eisenpulver. Spezial-Glühversuche ergaben, daß bei der Lagerung beider Werkstoffe in Reinst-Stickstoff dieser selbst keinen Einfluß auf die Oxydationsneigung des Eisens ausübst. Die Verhinderung der Pyrophorität von Eisenpulver durch Lagerung in technischem Stickstoff wird auf eine langsam, feinbaulich geregelt aufwachsende Oxydschicht durch im Stickstoff vorhandene Sauerstoffspuren zurückgeführt.

    Description / Table of Contents: On the Electro Chemical Processes of the Inhibiting Effectivity of Minium or IronElectro chemical investigations to explain the protective properties of minium showed that PbO2 is ineffective as its high electric conductivity is causing local cells. A further result was that lead in natural waters may be less noble than iron.Minium may be reduced to metallic lead by corrosion currents as published by Dechaux. Minium acts as a depolarizer and will be reduced anodically by divalent iron which is generated in the corrosion process. The so formed compounds of divalent lead are generating protective covers on the basic metal. These covers are of high importance of the protection against corrosion.
    Notes: Elektrochemische Messungen zur Aufklärung der besonderen korrosionsschützenden Wirkung der Bleimennige haben ergeben, daß das Blei (IV)-oxyd jene Wirkung nicht hat, weil dessen hohe elektrische Leitfähigkeit die Bildung von Lokalelementen am Eisen bedingt. Ferner ist festgestellt worden, daß in den natürlichen Wässern das Blei unedler sein kann als das Eisen.Die Bleimennige kann durch Korrosionsströme zu metallischem Blei reduziert werden in Übereinstimmung mit Befunden von Déchaux. Die Bleimennige wirkt kathodisch depolarisierend und wird anodisch von dem bei der Korrosion entstehenden, zweiwertigen Eisen reduziert. Die gebildeten Verbindungen des zweiwertigen Bleis bilden auf dem Grundmetall Deckschichten. Diese sind für den Korrosionsschutz von ausschlaggebender Bedeutung.

    Description / Table of Contents: Corrosion Testing of Chemically Resistant Steels in LiquidsThe corrosion of chemically resistant steels in the industry can restrictively be estimated by means of laboratory experiments. Several series of experiments show in which way different factors influence the results of the corrosion tests.For metallurgical reasons the specimens must first of all be subjected to a complete glowing treatment and may not be deformed. The state of the surface and its chemical treatment influence essentially the results of the corrosion testsExactly defined experimental directions are a condition to achieve reproducebility. Impurities, differing position, motion or airation as well as differing duration of experiment are causing very much deviating losses of weight.By means of a very simple testing device the resistancy of some well known Cr-Ni-steels in the most usual mineral acids was determined and is represented in diagramms which allow to compare the steels and will advise the constructory of the chemical industry.
    Notes: Der Korrosionsangriff chemisch-beständiger stähle in der Industrie kann durch Laboratoriumsversuche nur mit Einschränkungen vorausgesagt werden. An Hand mehrerer Versuchsreihen wird gezeigt, in welchem maße sich verschiedene Einflußgrößen auf die Ergebnisse der Korrosion auswirken.Auf der metallurgischen Seite ist in erster LInie auf vollständige Glühbehandlung und Vermeiden jeder Verformung der Proben zu achten. Der Zustand der Oberfläche und ihre chemische Behandlung ist auf die Ergebnisse der Korrosionsprüfng ebenfalls von großem Einfluß.Eine genau definierte Versuchsdurch-führung ist für die Wiederholbarkeit der Versuche Voraussetzung. Verunreinigungen, verschiedene Lage der Proben, unterschiedlichen Bewegung oder Belüflung und verschiedene Versuchsdauer haben stark abweichende Gweichtsverluste zur Folge.Mit einer einfachen Versuchsanordung wurden Beständigkeitsschaubilder bekannter CrNi-Stähle in den gebräuchlichsten Mineralsäuren aufgenommen. Diese Gegenüberstellung kann zum Vergleich der Stahlmarken und für den Apparatebauer der chemischen Industrie ein Anhaltspunkt sein.

    Description / Table of Contents: The use of elektrolytic tinplateIn the introduction the enormous change of the manufacturing process of tinplate is dicussed which resulted in the introduction of the cold reduction process for the steel  -  changing from the steel sheet to the continuous steel strip  -  and in the electroplating of tin. There is a very different behaviour in service through the decreasing of the tin coating weight which is now less than a third of that of a hot-dip tinplate. The structure of the different surface layers of tinplate and their properties are discussed. There are considerale differences in solderability, in the tension for rusting of the exterior of tin cans and also in the corrodibility in the interior of such cans. Differences in the surface quality of the steel strip are of special importance. To avoid such defects the electrolytic tinplate is proteted in most cases by lacquer coatings. Other possibilities are the use of combinations of hot-dip and electrolytic tinplate resp. the use of „differential“ electrolytic tinplate.
    Notes: Einleitend wird auf die unwälzende Änderung der Herstellungsverfahren für Weißblech eingegangen, die sich durch die Einführung des Kaltwaltzverfahrens für den Stahl  -  Übergang von der Blechtafel zum kontinuierlichen Band  -  und der elektrolytischen Verzinnung während des zweiten Weltkrieges ergeben haben. Durch die Verringerung der Zinnauflage auf weniger als ein Drittel der bei der Feuerverzinnung üblichen Menge ergibt sich ein sehr unterschiedliches Verhalten. Besprechung des Aufbaus der verschiedenen Oberflächenschichten. durch die verschieden hohe Zinnauflage ergeben sich erhebliche Unterschiede in der Korrosion im Innern von solchen Dosen. wichtig snd vor allem die Fragen der Oberflächenunterschiede im Stahlblech. Zur Vermeidung dieser Fehler wird Elektrolyt-Weißblech in sehr vielen Fällen durch Aufbringung eines Lacküberzugs geschützt. Andere Maßnahmen sind die Verwendung von Kombinationen von feuerverzinntem und Elektrolyt-Weißlech bzw. die Verwendung von „Differenz“-Weißblech.

    Description / Table of Contents: Indications on how to treat and how to use platinium crucibles and traysThe durability of laboratory instruments like crucibles, trays, tongs etc. made of platinium could be prolonged by proper and suitable treating. To avoid high temperatures, greasy storage places and the effect of smoking flames and reducing atmospheres will be as useful as to take precautions in the mechanical removal of melting remainders, Numerous experiments could be carried out in platinium vessels without any danger for the material if you know and regard its pecularities.
    Notes: Die Lebensdauer von Laborgeräten wie Tiegeln, Schalen, Zangen usw. aus Platin kann durch sachgemäße Behandlung wesentlich verlängert werden. Vermeidung hoher Temperaturen, verschmutzter Abstellflächen und des Einflusses rauchender Flammen und reduzierender Atmosphären sind ebenso nützlich wie Vorsicht bei der mechanischen Entfernung von Schmelzrückständen. Zahlreiche Reaktionen lassen sich in Platingefäßen ohne Gefahr für den Werkstoff ausführen, wenn man dessen Eigenarten kennt und ihnen in geeigneter Weise Rechnung trägt.

    Description / Table of Contents: Top Corrosion Resistant Alloys in Coal by Product PlantsThe Harpener Bergbau AG. in Dortmund has introduoced a new method for the deslfurization of ammonia gas. The device consists of a pressure column with a diameter of 600 mm and a height of 12 m and some accessory apparatus.The customary materials as there are among others austenitic, stainless and acid proof steels which had been used in the beginning, did not comply with the requirements of resistancy. They had heen deteriorated due to corrosion in the run of some months. So the qualifications of the Hastelloy alloys were tested. Corrosion experiments under working conditions ( -  in ptc.  -  20 NH3, 12 H2S, 6 CO2 mar. 2 HCN, 160-180°C, 13 atm) show that the loss by corrosion of Hastelloy C ( - in ptc.  -  60 Ni, 16 Mo, 16 Cr, 4 W) amounts to 0,0014 g/m2/day.So the plant was build of Hastelloy C. The test of the Technical Supervision Association T Ü V confirmed the results of the stadard analysis and determined following values in their mechanic test: yield point 48,3 mg/mm2. tenacity 83,5 kg/mm2, extension 56 ptc. The results of the pressure test with 15,6 kg/cm2 as well as the X ray test of the welding seams were positive.The plant has been in operation without any damage since October 1955. The good properties of Hastelloy induced the company above metioned to build furter plants of this material.
    Notes: Ein neues Druckverfahren für die Entschwefelung von Ammoniakgas wurde bei der Harpener Bergbau A.G., Dortmund, eingeführt. Bei der Anlage handelt es sich im wesentlichen um eine Druckkolonne von 600 mm Durchmesser und 12 m Höhe sowie einige Nebenapparaturen.Die anfänglich für den Bau verwendeten herkömmlichen Werkstoffe, u. a. auch austenitische rost- und säurebeständige Stäble, genügten den Anforderungen nicht. Sie wurden mitunter bereits nach wenigen Monaten durch Korrosion zerstört. Es wurde deshalb die Eignung der Hastelloy-Legierungen überprüft. Korrosionsversuche unter Betriebsbedingungen (in [%] 20 NH3, 12 H2S, 6 CO2, max. 2 HCN; 160 bis 180° C; 12 atü) ergaben bei Hastelloy Alloy C (mit [%] 60 Ni, 16 Mo, 16 Cr, 4 W) einen Korrosionsverlust von 0,0014 g/m2·h.Die Anlage wurde daraufhin in Hastelloy C erstellt. Die T.Ü.V.-Prüfung bestätigte die Werte der Soll-Analyse und ermittelte bei der mechanischen Prüfung folgende Werte: Streckgrenze 48,3 kg/mm2, Zugfestigkeit 83,5 kg/mm2, Dehnung 56%. Die Druckprüfung mit 15,6 kg/cm2 Wasserdruck sowie die Röntgenprüfung der Schweißnähte ergab keine Beanstandungen.Die Anlage ist seit Oktober 1955 in Betrieb und arbeitet seither ohne Anstände. Das gute Verhalten des Werkstoffes Hastelloy veranlaßte das vorgenannte Unternehmen, inzwischen weitere Anlagen hieraus herstellen zu lassen.

    Description / Table of Contents: The Tensile Corrosion and the Theory of TenacityTensile corrosion cracks are dependent of time. The condition of breaking is the mathematical product of mechanic and chemical wear. The mechanic wear exerts the maintenance of the flowing conditions during the corrosive attack. This can be described by an exponential dependence of the tensile stress. The chemical wear is the product of the effectivity (electro chemical potential) and the concentration of the corrosive agent, the time of attack and the influence of temperature. The latter is determined by the energy of activation of the process.The corrosion crack is theoretically a tensile crack just like the red shortness (weld crack) and the solder crack. the conditions of occurence of these kinds of cracks are (1) the presence of two different kinds of atoms in the same lattice and (2) the presence of elastic and overelastic tensions. the dependence of the linkage of the foreign atoms on the state of stress is of decisive influence upon the probability of breaking. As foreign atoms influence the elastic limit and the flowing properties each overelastic treatment causes an alternation of their linkage and also a change of the electrochemical potential which is a decisive factor of the tensile corrosion.
    Notes: Der Spannungskorrosionsbruch ist ein Zeitstandbruch. Bruchbedingung ist das mathematische Produkt von Mechanischer und chemischer Beanspruchung. Die mechanische Beanspruchung bewirkt die Aufrechterhaltung der Fließbedingung während des Korrosionsvorganges, wobei eine Exponentialfunktion der Spannung maßgebend ist. Die chemische beanspruchung ist das produkt aus Wirksamkeit (elektrochemischem Potential) und Konzentration des Angriffsmittels, Angriffsdauer und Temperatureinfluß, wobei der letztere durch die Aktivierungsenergie Vorganges bestimmt ist.Festigkeitstheoretisch gehört der Korrosionsbruch zu den Spannungsbrüchen, zu denen auch der Rotbruch (Schweißriß) und der Lötbruch gehören. Bedingung für das Auftreten dieser Brucharten ist 1. das Vorhandensein von zwei verschiedenen Atomarten im gleichen Gitter und 2. das Vorhandensein von elastischen oder überelastischen Spannungen.  -  Maßgebend für die Bruchgefahr ist die Abhängigkeit der Fremdatombindung im Raumgitter vom Beanspruchungszustand. Da die Fremdatome die Elastizitätsgrenze und das Fließverhalten bestimmen, führt jede überelastische Beanspruchung eine Veränderung ihrer Bindung Herbei. Der dabei entstehende Potentialunterschied ist für die Spannungskorrosionsgefahr maßgebend.

    Description / Table of Contents: The corrosion of soft steel in alkali mono- und alkali hydrogen fluorides I. The influence of the concentration of the solution upon the corrosion of soft steelThe influece of the concentration of alkali mono  -  and alkali hydrogen fluoride solutions upon the corrosion of soft steel has been investigated. In all solutions a corrosive attack is taking place. It depends on the concentration of the soultion. The corrosion velocity  -  concentration diagramm shows a characteristic tershold value which is followed by an approximation to a minimum. In KF- and KF·HF solutions corrosion resistant covers are formed finally while in (NH4)F HF solutions even at relatively high concentrations a corrosive attack was recorded.
    Notes: Untersucht wurde der Einfluß der Konzentration von Alkalimono- und Alkalihydrogenfluorid-Lösungen auf die Korrosion von Weichstahl. In allen Lösungen kommt es zu einem konzentrationsabhängigen Angriff. Die Korrosionsgeschwindigkeit-Konzentrationskurve weist einen charakteristischen Schwellenwert auf, nach dessen Überschreiten strebt die Korrosionsgeschwindigkeit- Konzentrationskurve einem Minimum zu. In KF- und in KF · HF-Lösungen kommt es schließlich zur Ausbildung korrosionsschützender Deckschichten, während in (NH4)F · HF-Lösungen selbst bei verhältnismäßig hohen Konzentrationen noch ein gewisser Angriff zu verzeichnen ist.

    Description / Table of Contents: On the behavior of materials upon hydrogen fluoride and hydrofluoric acidNumerous papers, published within the previous five years, and industrial experience allow to draw a picture of our knowledge of the behavior of materials upon hydrogen fluoride and hydrofluoric acid. Not alloyed steels, nickel, coper, silver and lead are resistent to hydrofluoric acids of moderate concentrations. Ingot steel is resistent even to acids of more than 65 pct. Aluminum and titanium are deteriorated by hydrofluoric acids of all concentrations though they are more or less resistent to dry hydrogen fluoride just like the metals, first mentioned, except lead. Except of the silica cements all acid proof cements and especially the plastic cements with carbon filling could be used in hydrofluoric acid engineering. Natural and synthetic rubber are materials qualified to build hydrofluoric acid containers of. Plastics like pvc, polythylene, polyfluorethylene and some more are qualified to be used in presence of hydrofluoric acid of less than 50 pct. at moderate temperatures.
    Notes: Aus den zahlreichen Veröffentlichungen der letzten 5 Jahre und praktischen Betriebserfahrungen ergibt sich ein Bild unseres heutigen Wissens über das Verhalten der Werkstoffe gegenüber wäßriger Flußsäure und wasserfreiem Fluorwasserstoff. Unlegierte Stäble, Nickel, Kupfer, Silber und Blei sind gegen mäßig konzentrierte Säure beständig; Flußstahl auch gegen solche von 〈 65%. Aluminium und Titan werden von flußsäure aller Konzentrationen zerstört, sind jedoch gegenüber wasserfreiem Fluorwasserstoff  -  ebenso wie die zuerstgenannten Metalle mit Ausnahme von Blei  -  mehr oder weniger resistent. Säurefeste Kitte und Zemente sind  -  für die Anwendung gegenüber Flußsäure geeignet, besonders die Kunststoff-Kitte mit Kohlenstoff-Füllung. Natur- und Synthesekautschuk dienen als Werkstoff für Lager- und Transportbehälter. Von den Kunststoffen eignen sich PVC, Polyäthylen, Polyfluoräthylene und einige andere für die Handhabung 〉 50%iger Flußsäure bei mäßigen Temperaturen.

    Description / Table of Contents: Investigations on the Current Density Distribution of Cathodic Protection in Different SoilsIf you want to apply cathodic protection with extern source of current to buried iron constructions or pipelines economical reasons make it desirale to carry out orienting experiments to calculate the consumption of current and the current density distribution to be expected. The experimental cell consisting of a piece of a steel tube and a parallel auxiliary anode was buried in soils of different chemical properties. The cathodic polarization curves were measured by means of the Holler method. The potentials of different spots were measured under certain extern current intensities by point source anodes. The most favorable conditions of a homogeneous current density distribution in soils will be achieved when there is a big decline of the polarization potential. This is in close connection to the result o the corrosion control experiments in the soils referred to.
    Notes: Bei dem kathodischen Korrosionsschutz eiserner Untergrundanlagen und Rohrleitungen mit äußerem Strom ist es aus wirtschaftlichen Gründen zweckmäßig, schon vorher solche Orientierungsversuche durch-zuführen, mit Hilfe deren man den Strombedarf und die zu erwartende strom-verteilung des Schutzes ermitteln kann. Die Versuchszelle bestand hier aus einem Stahlrohr, das zusammen mit einer parallelen Hilfsanode in Böden mit verschiedenen chemischen Eigenschaften verlegt wurde. Mit der von Holler beschriebenen Meßmethode wurden die kathodischen Polarisationskurven, und, mit Hilfe einer Punktanode, die Potentiale an verschiedener Beobachtungsstelle bei gegebener äußerer Stromstärke gemessen. Die günstigsten Bedingungen für die gleichmäßige Stromverteilung sind im Boden zustande-gekommen, in dem sich die Wirkung der Polarisations-Potentialfälle am stärksten zeigte. Dies stand in engem Zusammenhang mit den Versuchsdaten bezüglich der Steuerung der Korrosion in den betreffenden Böden.

    Description / Table of Contents: Polyvinylchloride Plastik PipesPipes of polyvinylchloride (Supradur) are gaining increasing application in contructions for transport of aggressive liquids and gases because of their good properties especially owing to their resistance to corrosion. So this paper presents a general and up to date survey of the commercial types and their dimensions and of the physical and corrosion chemical behavior as well as the methods of installation and fitting of polyvinylchloride pipes.
    Notes: Rohre aus Polyvinylchlorid (Supradur) finden infolge ihrer guten allgemeinen und spezifischen Eigenschaften, insbesondere ihres ausgezeichneten Korrosionschemischen Verhaltens, zunehmende Verwendung in Anlagen zur Förderung aggressiver Flüssigkeiten und Gase. Im Hinblick darauf gibt der vorliegende Fortschrittsbericht einen zusammenfassenden und zeitgemäßen Überblick über Lieferarten und Dimensionierung, über das physikalische und korrosionschemische Verhalten sowie über die Verlegung und Verbindung von Polyvinylchlorid-Plastikrohren.
