    Description / Table of Contents: Synthetic Rubber Products for Protection against CorrosionIn the chemical and similar industries reaction vessels, pipe lines etc. are covered preferably by genuine or synthetic high polymers. The methods being used nowadays to achieve protection against corrosion are very numerous. The covers are made of buna, perbunan, neoprene, butyl rubber, hypalon and hycar. Covers of these materials can be vulcanized. They are resistant to sulfuric acid, acetic acid, potassium hydroxide, chlorine etc. The connection between metal and cover must be totally homogeneous. Otherwise serious interruptions of work might occur. The synthetic high polymers will have to be applied according to certain directions. The techniques of mixing and working and vulcanization are determining the quality of the covers.There are the brass, Dartex and Desmodur methods as well as the silicone covers and the hypalon cermections.Being vulcanised the densisity of the covers is tested by means of an inductive machine. The testing voltage amounts to 2000 volts corresponding to a spark gap of 20 mm.
    Notes: In der chemischen und den verwandten Industrieen werden Reaktionsgefäße, Rohrleitungen und dgl. vorzugsweise mit natürlichen oder synthetischen Hochpolymeren belegt. Die Verfahren, die beute als Korrosionsschutz angewendet werden, sind sehr mannigfaltig. Solche Schutzbeläge werden hergestellt:Aus Buna, Perbunan, Neoprene, Butylkautschuk, Siliconkautschuk, Hypalon, Hycar.Diese Beläge sind vulkanisierbar und beständig gegen:Schwefelsäure, Salzsäure, Flußsäure, Essigsäure, Kalilauge, Chlor usw.Die Verbindung zwischen Metall und Schutzbelag muß vollständig homogen sein, da sonst im Betrieb erhebliche Störungen auftreten können. Die synthetischen Hochpolymere müssen nach ganz bestimmten Vorschriften der Verarbeitung eingesetzt werden. Die Technik der Mischungen, die Verarbeitung und schließlich die Vulkanisation sind für die Güte der Beläge ausschlaggebend.Man kennt das Messingverfahren, das Dartex-Verfahren, das Desmodur-Verfahren, die Siliconbeläge und die Hypalon-Bindungen.Die fertigen Beläge werden nach der Vulkanisation mit einem Induktionsapparat auf Dichtigkeit geprüfl. Die Prüfung erfolgt bei 2000 V-Spannung, die etwa einer Funkenstrecke von 20 min entspricht.

    Description / Table of Contents: The Methods of Testing CorrosionFor a useful application of materials it is necessary to know their resistance to corrosion and the effects of the protective measurements. Corrosion tests in shop experience are very long termed and the condition of attack are influenced by difficulty attainable, natural modifications so that no reproducible results are gained. Laboratory experiments are necessary to characterize the chemical properties of materials under constant and reproducible conditions in shorter time. The conditions of testing must be adapted to those of practice if useful results shall be obtained.The atmosphere is the most important agent which influences the wear of materials. There is a description of several testing methods which have been developed to imitate climatic conditons. In every case it seems to be useful to indicate the resistance to corrosion not only from the results of a single testing method. Several methods working on different bases should be selected and according to their results you can apply the materials concerned.
    Notes: Für den zweckmäßigen Einsatz der Werkstoffe sind Angaben über seine Korrosionsbeständigkeit und gegebenenfalls auch über die korrosionsschützende Wirkung von Schutzverfahren nötig. Korrosionsversuche in der Praxis erfordern jedoch häufig sehr lange Zeiten und die Angriffsbedingungen sind vielfach einem natürlichen, schwer erfaßbaren Wechsel unterworfen, so daß keine reproduzierbaren Ergebnisse erhalten werden. Laboratoriumsversuche sind deshalb nötig, um die chemischen Eigenschaften der Werkstoffe in kürzeren Zeiten bei gleichartigen, reproduzierbaren Prüfbedingungen kennzeichnen zu können. Die Prüfbedingungen im Laboratorium müssen aber den praktischen Beanspruchungen angepaßt sein, wenn auswertbare Ergebnisse erhalten werden sollen.Eine der wichtigsten Beanspruchungen der Werkstoffe beim praktischen Gebrauch ist die Atmosphäre. Um klimatische Bedingungen im Laboratorium nachzuahmen, sind verschiedenartige Prüfverfahren entwickelt, die im einzelnen beschrieben werden. In jedem Falle erscheint es zweckmäßig, die Korrosionsbeständigkeit nicht nur auf Grund des Verhaltens eines Prüfverfahrens anzugeben, sondern mehrere Prüfverfahren mit unterschiedlichen Bedingungen zu wählen und nach den Ergebnissen dieser Prüfungen die Werkstoffe in der Praxis einzusetzen.

    Description / Table of Contents: The Rest Potentials and the Cathodic Polarizations of Active Chrome and a Chrome Iron Alloy in Sulfuric AcidThe cathodic polarization curves and the rest potentials of active chrome and a chrome iron alloy (25,6 pct chrome) were measured in dependance of the pH-value of the electrolyte. The behavior of the rest potential deviates from that of the hydrogen electrode. By means of the factors α and β they can be explained for the deposition of hydrogen as well as for the dissolution of metal. The equation of the rest potential is \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm V}_{\rm o} = {\rm B} - \frac{{0,058}}{{2\,\alpha + \beta }} \cdot {\rm p}_{\rm H} $$\end{document} where B is a constant factor. The sum 2 α - β is usually greater than 1.In the range of the pH-values investigated the cathodic polarization curves of the deposition of hydrogen are parallel. The exchange currents calculated from the logarithmic representation of the polarization curves rise with increasing concentration of the acid and increasing content of chrome in the alloy. The evaluation of the experimental results was carried out according to theroretical principles which had been applied successfully before.
    Notes: An aktivem Chrom und einer Eisen Chrom-Legierung mit 25,6%; Cr wurden in Abhängigkeit vom pH-Wert die Ruhepotentiale gemessen und kathodische Polarisationskurven aufgenommen. Die Ruhepotentiale zeigen ein gegenüber der reversiblen Wasserstoffelektrode abweichendes Verhalten, das mit Hilfe der Durchtrittsfaktoren α und ß für die H2-Entwicklung und für die Metallauflösung gedeutet werden kann. Es gilt für das Ruhepotential \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm V}_{\rm o} = {\rm B} - \frac{{0,058}}{{2\,\alpha + \beta }} \cdot {\rm p}_{\rm H} $$\end{document} mit B =const. Die Summe 2α+β ist in der Regel 〉 1.Die kathodischen Polarisationskurven der H2-Entwicklung verlaufen im untersuchten pH-Bereich parallel. Die aus der logarithmischen Darstellung ermittelten Ausgleichsströme, die der Korrosion entsprechen, steigen mit wachsender Säure-konzentration und mit wachsendem Cr-Gehalt der Eisen-Chrom-Legierung stark an. Die Auswertung der Versuchsergebnisse erfolgte nach den in letzter Zeit mit gutem Erfolg verwendeten kinetischen Ansätze.

    Description / Table of Contents: The Intercrystalline Corrosion and teh Attack at Grain BoundariesThe intercystaline corrosion in dependence of the degree of desorientation of touching grains was investigated by means of an Al Mg alloy which was made susceptible to intercystalline corrosion by heat treatments. The experiments show that the intercrystalline attack depends very much on the degree of desorientation especially at 4 and 16°. The results being explained by the lattice energy and the lattic structure theories allow to make a distinction between fine, micro and macro angle grain boundaries. The author shows finally that the intercrystalline attack will be caused by the type and form of inhomogeneous corings of one or more phases at grain boundaries of more than 5° but not by the elastic-potential lattice energy.
    Notes: Untersucht wurde die Abhängigkeit der interkristallinen Korrosion vom Desorientierungsgrad sich berührender Kristallkörner an einer durch Wärmebehandlung interkristallin anfällig gemachten AlMg-Legierung. Die Versuchs ergaben grundsätzlich eine starke Abhängigkeit des interkristallinen Angriffs vom Desorientierungsgrad mit Angriffsspitzen bei 4 und 16°. Die Versuchsergebnisse, die gitterenergetisch und gittergeometrisch erklärt werden, führen zur Unterscheidung vou Fein-, Klein- und Großwinkel-Korngrenzen. Schließlich wird gezeigt, daß die clastisch-potentielle Gitterenergie den interkristallinen Angriff nicht ursächlich bestimmt, sondern die Art und Form sich bildender inhomogener Entmischungen ein- und vielphasiger Art an Korngrenzen über 5°.

    Description / Table of Contents: The corrosion Chemical Behavior of Nonferrous Metals upon Alkalimono-and Alkali Hydrogen Fluorides II. The Corrosion Chemical Behavior of Aluminium in Hydrochloric Acid and Sodium Hydroxide Solutions Containing Alkalimono- and Alkali Hydrogen FluoridesStarting from investigations on the solubility of Al, Al Mg Si and Al Mg alloys especially in KF-solutions of different concentrations  -  After a short duration of action teh metals mentioned will be protected against further attack effectively by dense, well adhering covers.  -  the inhibition of the attacks of 0.1 n HCL and 0.1 n NaOH solutions upon pure Al (99.9) were tested under stationary conditions by addition of different quantities of KF-resp. KF. HF-resp. NH4F.HF. While the metal will suffer no attack in KF-solutions, slight attack in KF.HF-solutions and strong attack in NH4F.HF-solutions additions of KF.HF or NH4F.HF do not influence the solvation of Al (99,9) in 0.1 n HCl in 0.1 n NaOH solutions little additions of fluorides suppress the attack intensely. Under good conditions teh decrease amounts to 98 pct.
    Notes: Ausgehend von Lösungsversuchen mit Al, AlMgSi- und AlMg-Legierungen insbesondere in KF-Lösungen verschiedener Konzentration, bei denen schon nach kurzer Einwirkungsdauer dichte, guthaftende Fluoridschichten die Versuchsmetalle vor dem weiteren Angriff wirkungsvoll schützten, wurde die Inhibition des Angriffs von 0,1 n-HCL und 0,1 n-NaOH auf Rein-Al 99,9 durch Zusatz unterschiedlicher KF- bzw. KF·HF-bzw. (NH4) F.HF-Mengen im Standversuch überprüft. Während der Versuchs-Werkstoff in KF-Lösungen nicht, in KF.HF-Lösungen mäßig und in (NH4)F.HF-Lösungen stark angegriffen wird, beeinflussen KF-, KF.HF- oder (NH4)F.HF-Zusätze das Inlösunggehen von Al 99,9 in 0,1 n-HCL nicht. In 0,1 n-NaOH kommt es dagegen meist schon nach Zusatz geringer Fluoridmengen zu einer starken Inhibition des Angriffs, die unter günstigen Verhältnissen einer Hemmwirkung von 98% entspricht.

    Description / Table of Contents: Elchemographic Measurements in Corrosion ResearchThe effects of corrosion and passivity on metals and their alloys can be described and explained in certain cases by means of experimentally established electro chemical theories. For these and other electro chemical problems an elchemographic design has been experienced. This apparatus allows a continuous photographic recording of potentials and currents under eligible modification of the conditions of polarization.Elchemographic measurements are based on electrode polarizations by means of discontinuous currents which can be modified over a wide range.Polarization by means of discontinuous current makes it possible to measure the electrode potential in the dead state. This is of great importance to the research of corrosion and passivity as well as of transient resistants which generate the Ohm voltage and the well known component of the potentials measured under polarization.The elchemographic measurements have been extended to capacitive systems. In this connection the influences of a capacity on polarization current and potential were investigated. The results can be used in connection with the theory of local cells. (Influence of a capacity between two equipotential areas.)
    Notes: Die an Metallen und deren Legierungen beobachteten Korrosions- und Passivitätserscheinungen kann man in bestimmten Fällen durch experimentell belegte elektrochemische Anschauungen treffend beschreiben und erklären. Hierbei und auch bei anderen elektrochemischen Geschehen, bewahrte sich eine elchemographische Vorrichtung, die eine kontinuierliche photographische Registrierung der Potential- und Stromwerte bei wählbaren Änderungen der Polarisationsbedingungen ermöglicht.Elchemographische Messungen basieren auf einer Elektrodenpolarisation mit unterbrochenem Strom von rechteckartigem Verlauf unter Bedingungen, die es gestatten, den Polarisationsstrom weitgehend zu ändem.Die Polarisation mit unterbrochenem Gleichstrom ermöglicht die Bestimmung des Elektrodenpotentials in stromlosem Zustand, das für Korrosions- und Passivitätserscheinungen grundlegende Bedeutung, ebenso wie die vorübergehenden Widerstände, welche die Ohmsche Spannung bedingen und die gewohnte Komponente der an polarisierten Elektroden gemessenen Potentialwerte darstellen.Die elchemographischen Messungen wurden auf kapazitative Systeme ausgedehunt, in diesem Zusammenhang wurde der Einfluß einer Kapazität auf Polarisationsstrom und Potential untersucht. Die Versuchsergebnisse kann man im Zusammenhang mit der Konzeption der Lokalelemente (Eingriff einer Kapazität zwischen zwei äquipotentialen Flächen) anwenden.

    Description / Table of Contents: Investigation of the Comparative Inhibiting Effect of Organic Compounds in Aqueous SolutionsTests were made to determine the protective effect of a number of organic compounds, of different types on the corrosion of steel sheet in aqueous solution. The rate of corrosion was estimated by weight loss. The effect of the concentrations and pH values of the solutions on the initiation of corrosion was also determined. It was found that the protective effect of alkaline compounds was determined by the minimum basicity of the solution. Acid compounds, tested in the form of their sodium salts, were protective if their dissociation constants lay within a certain range.
    Notes: Eine Reihe organischer Verbindungen aus verschiedenen Verbindungsklassen wurde auf die Schutzwirkung gegenüber der Korrosion von Eisenblech in wäßrigem Medium geprüft. Die Korrosionsgeschwindigkeit wurde durch Bestimmung des Gewichtsverlustes der Blechproben ermittelt. Ferner wurde die Abhängigkeit des Korrosionsbeginns von der Konzentration der zu untersuchenden Verbindung und vom pH-Wert ihrer Lösungen untersucht. Bei basischen Verbindungen war die Schutzwirkung im allgemeinen vom Überschreiten einer Mindestbasizität der Lösung abhängig. Bei sauren, in Form ihrer Natriumsalze untersuchten Verbindungen trat eine Schutzwirkung dann ein, wenn die Dissoziationskonstante innerhalb eines bestimmten Bereiches lag.

    Description / Table of Contents: The Construction, Method of Use and Range of Applicability of a New Bend Test ApparatusThe technical importance of bend testing is discussed. The construction, method of use and standardisation of a new universal bend test apparatus are then described in detail. Test results on ferrous and non-ferrous metals and on organic substances demonstrate the universal applicability of the test apparatus. Examples of stress-strain curves and of the determination of elastic modulus and moment of inertia are given.
    Notes: Einleitend wird auf die technische Bedeutung des Biegeversuchs für die Werkstoffprüfung hingewiesen. Anschließend werden Aufbau, Arbeitsweise, Eichung und Einsatz eines neuen Universal-Biegeprüfers in allen Einzelheiten behandelt. Ein ausführlicher wiedergegebenes, an E- und NE-Metallen sowie organischen Werkstoffen (Kunststoffe, Holz) erhaltenes Versuchsmaterial belegt sinnfällig die universelle Anwendung (Aufnahme von Biegespannungs-Durchbiegungs-Diagrammen, E-Modul- und Trägheitsmoment-Bestimmungen) des beschriebenen Biegeprüfers.

    Description / Table of Contents: Designing of Constructions to Make Painting and Protection against Rust Easy (Protection against Rust Begins at the Drawing Board)Construction elements like inaccessible corners and narrow slits should be prevented. To avoid waterbags, channal and angle irons shall be arranged with their openings showing down. Acute angles and connections of lattice masts, tube bridges, and supports which cannot be cleaned easily are unsatisfactory for painting. You should prefer welded constructions to riveted ones, and tube constructions to those made of sectional iron. Horizontal surfaces are endangered by staying water, depositions of dust and soot, and mossy growth. Smoke gases should be kept off railway bridges by wooden shields. Riveted joints and slits must be sealed; bases of girders may not be set in concrete. Suspensors for scaffolds will help to reduce the costs of renovation. Stationnary cars on the underframe of bridges are very useful. Covered girders as well as overlapping joints, and nodal sheets must be painted before they are installed.Welded constructions have advantageously less starting points for rusting than riveted ones because rivet heads are very often the points of precocius rusting.
    Notes: Zu vermeiden sind unzugängliche Ecken und schmale Fugen. U-Eisen und Winkeleisen sollen mit der Öffnung nach unten angeordnet werden, um Wassersäcke zu vermeiden. Anstrichtechnisch mangelhaft sind auch spitze Winkel und schwer zu reinigende Anschlüsse bei Gittermasten, Rohrbrücken und Stützen. Geschweißte Konstruktionen sind den genieteten vorzuziehen, Rohrkonstruktionen solchen aus Profileisen. Waagerechte Flächen sind durch Wasseransammlungen, Staub- und Rußablagerung und Bildung von Moospolstern gefährdet. Bei Eisenbahnbrücken sind Rauchgase durch Holzschilder abzuwehren. Nietstellen und Fugen sind gut zu verkitten, Trägerfüße sind zweckmäßig nicht einzubetonieren. Durch Aufhängevorrichtungen für die Rüstung kann der Erneuerungsanstrich verbilligt werden. Bei Brücken sind stationäre Wagen zur Befahrung der Unteransicht am Platze. Verdeckte Träger sowie sich überdeckende Laschen und Knotenbleche müssen den endgültigen Anstrich vor der Montage erhalten.Geschweißte Konstruktionen haben gegenüber genieteten den Vorteil, weniger Ansatzpunkte zur Rostbildung zu bieten, während im besonderen Nietköpfe häufig Ausgangspunkte vorzeitigen Rostens sind.

    Description / Table of Contents: Vibration Method to Detect Modifications in WoodThe authors investigated the influence of an impregnation by a synthetic resin or boric acid, a watering and the effects of alkali and mineral acids upon the torsional fatigue strength (modulus of elasticity in shear and logarithmic decrement) of numerous exotic hard and soft wood. While an impregnation makes the modulus of elasticity in shear raise watering and boric acid treatments diminish the logarithmic decrement but cause high torsional fatigue strength. The alkali resistance of numerous wood is generally much lower than their resistance to acids.
    Notes: Die Verfasser studierten den Einfluß einer Imprägnierung mit Kunstharz oder Borsäure, einer Wasserlagerung und der Einwirkung von Lauge und Mineralsäure auf die Torsionsschwingungsfestigkeit (Gleitmodul und logarithmisches Dekrement) zahlreicher exotischer Laub- und Nadelhölzer. Während Kunstharztränkung den Gleitmodul stark erhöht, erniedrigen Wasserlagerung und Borsäurebehandlung das logarithmische Dekrement und erhöhen die Torsionsschwingungsfestigkeit. Die Laugenbeständigkeit der verschiedenen Holzarten ist im allgemeinen erheblich geringer als deren Säurebeständigkeit.

    Description / Table of Contents: New Paints Based on PlasticsThe article  -  addressed to workers in the paint industry  -  is intended to show the increasing influence of chemistry upon the technological development of the industry. It shows that there is no longer a frontier between plastics and paints.The isocyanate reaction is mentioned as a classic example of “custom made” raw materials for lacquers.Epoxy resins also show possibilities for the development of particular desired properties owing to the variety of substances with which they interact.The unsaturatid poly ester resins show new possibilities for paints and varnishes.The plastosoles and organosoles  -  suspensions of poly vinyl chloride (pvc) in plasticizers  -  are used as a means wherebyly pvc-powder for plastics materials can be applied in paint technology.Epoxy resins, unsaturated poly esters and organosoles are discussed in detail to show the way in which the frontier between plastics and paints has been narrowed by the results of chemical research.
    Notes: Die Ausführungen  -  für den Lackverarbeiter gedacht  -  sollen den steigenden Einfluß der Chemic auf die technische Entwicklung in der Lackindustrie veranschaulichen. Die Betrachtung zeigt, daß zwischen „Kunststoff“ und „Lack“ keine Grenzen mehr bestehen.Die Isocyanat-Reaktion wird gestreift als ein klassisches Beispiel der Synthese von Lackrohstoffen „nach Maß“.Die Epoxyharze erschließen weitere Möglichkeiten, das „Baukasten-Prinzip“ anzuwenden infolge Variation der Reaktions-Komponenten.Die ungesättigten Polyesterharze zeigen neue Möglichkeiten sowohl auf dem Kunststoff- als auch auf dem Lack-Sektor auf.Das Beispiel der Plastisole und Organosole  -  Aufschlemmung von Polyvinylchlorid (PVC)-Pulver in Weichmacher  -  wird als ein Umweg beschrieben, mit dessen Hilfe ein für Kunststoffzwecke verwendetes PVC-Pulver einer lacktechnischen Verarbeitung zugeführt wird.Epoxyharze, ungesättigte Polyester und Organosole wurden eingehender behandelt, um zu zeigen, wie die Auswirkungen chemischer Forschung die Grenzen zwischen Kunststoff und Lack zum Verschwinden bringen.

    Description / Table of Contents: The Corrosion of Distillery EquipmentThe formation of hydrogen sulfide in alcoholic fermentation cannot be avoided. Part of the gas, set free during the distillation of the fermented mash, causes corrosion of the distillation apparatus. Copper is especially sensitive to hydrogen sulfide and in the course of time a considerable quantity of grayish black copper sulfide accumulates in the receiver of a copper still. Distillation apparatus is therefore now made of special corrosion resisting steels alloyed with chromium, nickel and molybdenum. Instead of copper sulfide, free hydrogen sulfide is now encountered and this must be led out by a pipe between the cooler and the receiver. The hydrogen sulfide left in the raw alcohol may attack the sensitive tinned spirit gauge. It is suggested that spirit gauges should also be made of corrosion resisting materials. The fermented mash (containing about 8 vol. pct. of alcohol) contains a maximum of 150 mg hydrogen sulfide per hectolitre. Two thirds are set free in the distillation of the mash. Refined spirit contains no hydrogen sulfide because the latter is totally volatilitised during the rectification of the raw alcohol. For removal of hydrogen sulfide use should be made of a patent of the Versuchs- und Lehranstalt für Spiritusfabrikation in Berlin. The alcohol, in steam- or in liquid-steam-phase, is passed through absorption chambers which contain active carbon, hydrated iron oxide and cement stones and in which the hydrogen sulfide is retained. There are thus methods of making the hydrogen sulfide harmless so that the corrosion of distillation and other equipment can be prevented.
    Notes: Bei der alkoholischen Gärung ist die Bildung von Schwefelwasserstoff nicht zu vermeiden. Ein Teil des Gases wird erst bei der Destillation der vergorenen Maische entbunden, wodurch Korrosionen an den Brenngeräten hervorgerufen werden. Kupfer ist besonders empfindlich gegenüber Schwefelwasserstoff. In der Spiritusvorlage eines Brenngerätes aus Kupfer sammelt sich daher im Laufe der Zeit eine erhebliche Menge grauschwarzen Kupfersulfids an. Infolge der Empfindlichkeit des Kupfers werden heute schon Destillier-Apparate aus mit Chrom, Nickel und Molybdän legierten Sonderstählen angefertigt, die Korrosionserscheinungen ausschließen. An Stelle des Kupfersulfids tritt nun etwas mehr freier Schwefelwasserstoff auf, der am besten zwischen Spirituskühler und Vorlage durch ein Luflrohr ins Freie abgeleitet wird. Von im Rohspiritus verbliebenem Schwefelwasserstoff kann jedoch auch die verzinnte und daher sehr empfindliche Spiritusmeßuhr angegriffen werden. Es wird vorgeschlagen, Spiritusmeßuhren ebenfalls aus korrosionsbeständigem Material anzufertigen. In der vergorenen Maische (etwa 8 Vol.-% Alkohol) ist höchstens mit etwa 150 mg Schwefelwasserstoff je hl zu rechnen. Etwa 2/3 davon werden bei der Destillation der Maische ausgeschieden. Im Feinsprit tritt kein Schwefelwasserstoff auf, da bei der Rektifikation des Robsprits restlose Verflüchtigung erfolgt. Zur Beseitigung des Schwefelwasserstoffs kann von einem Patent der Versuchs- und Lehranstalt für Spiritusfabrikation in Berlin Gebrauch gemacht werden. Der Sprit wird in der Dampf- oder Dampfflüssigkeitsphase in sogenannten Sorptionskammern durch Aktivkohle, Eisenoxydhydrat und Zementsteine geleitet, wobei der Schwefelwasserstoff gebunden wird. Es sind also Möglichkeiten vorhanden, den Schwefelwasserstoff unschädlich zu machen, so daß Korrosionen an Brenngeräten und Betriebsanlagen vermieden werden können.

    Description / Table of Contents: On the Influence of Anaerobic Bacteria on the Current Density of Cathodically Protected Equipment in SoilsThe usually applicable specifications for the cathodic protection of buried steel pipes must be modified if anaerobic soil bacteria are present in large quantities. The tests in soils containing high concentrations of sulfate reducing bacteria have shown that the current density, deduced from an initial polarization curve, does not garrantee sufficient protection. An increased protective effect was achieved in an inocculated culture medium when a more negative voltage was applied and maintained during the five months duration of the experiment. Some theoretical consequences are drawn from the experimental results obtained.
    Notes: Ist bei der Korrosion unterirdischer Stahlrohrleitungen mit der Anwesenheit anaerober Bodenbakterien in größerer Menge zu rechnen, dann bedürfen die sonst gut anwendbaren Kennzeichen des kathodischen Schutzes einer Modifizierung. Die zur Überprüfung des Schutzstrombedarfes durchgeführten Modellversuche in mit sulfatreduzierenden Bakterien angereichertem Boden haben ergeben, daß die sich aus zuvor aufgenommenen Polarisationskurven ergebende Stromdichte keinen genügenden Schutz sichert. Auf einem geimpften Nährboden ließ sich eine günstigere Schurtzwirkung erzielen, wenn ein entsprechend negatives Schutzpotential bei den Versuchsproben eingestellt und dessen Stabilität während der fünfmonatigen Versuche möglichst gesichert wurde. Aus den erhaltenen Versuchsergebnissen wurden einige theoretische Folgerungen gezogen.

    Description / Table of Contents: High Temperature Corrosion by Hydrogen Sulfide from Experiences in Petroleum RefiningBeing introduced 5-7 years ago the catalytic transforming and desulfuration methods of the oil industry produce new corrosion problems by the attack of hydrogen sulfide at high temperatures. The attack causes losses of metal and formation of voluminious crusts which block the passages and disturbe the transfer of heat. The type of crusts depends on the sort of steel used. The temperature and the concentration of the hydrogen sulfide (partial pressure) condition the degree of the sulfide corrosion for most part. Because the hydrogen phase, which contains much hydrogen sulfide, is circulating the concentration of the hydrogen sulfide in the reactor and the additional equipment is much higher than that of the hydrocarbon input. The limiting value of the hydrogen sulfide concentration below which the degree of corrosion is zero was found to be in the range of 0,006-0,008 mol pct. Increase of temperature causes rising corrosion. The concentration of hydrogen is of little influenze.  -  To avoid this corrosion you will have to desulfurize the input material (which is very expensive) or the circulating gas phase or to use hydrogen sulfide resisting metals. Highpercent chrome nickel alloys proved to be good except at high temperatures. For practical use 18/8 chrome nickel steel guarantees suficient resistance. Aluminum showing exceptionally good properties may not be used in pressure vessels. But it may be applied for coatings on low alloyed chrome steels by hot galvanization or calorization or by spraying which is but an insufficient method. Because low alloyed chrome and carbon steels are applied at critical spots for economical reasons the formation of crusts is unavoidable. They will be removed by chemical agents e. g. hydrogen chloride. Because of poisonous gases  -  hydrogen sulfide and sulfur dioxide  -  special precautions have to be taken.
    Notes: Durch die in den letzten 5 bis 7 Jahren bei der Erdölraffinierung neu eingeführten katalytischen Umformungs- und Entschwefelungsverfahren ist ein neues Korrosionsproblem durch Angriff des Schwefelwasserstoffs bei hohen Temperaturen entstanden. Dieser führt zu Metallverlust und zur Bildung voluminöser Schalen, welche die Durchgänge verstopfen und durch Belegen der Oberflächen Störungen des Wärmeüberganges verursachen. Die Art dieser Schalen ist verschieden je nach Art des zur Ausrüstung verwendeten Stahles. Temperatur und Schwefelwasserstoffkonzentration (Partialdruck) üben auf den Grad der Sulfid-Korrosion den größten Einfluß aus. Da bei den genannten neuen Verfahren die wasserstoffreiche Gasphase mit hohem Schwefelwasserstoffgehalt in den Prozeß zurückgeschickt wird, ist die Schwefelwasserstoffkonzentration im Reaktor und den Zuführungsapparaten größer als dem Schwegelgehalt der Kohlenwasserstoffspeisung entspricht. Ein Grenzwert der Schwefelwasserstoffkonzentration, unterhalb welchem der Korrosionsgrad praktisch null ist, wurde als im Bereich von 0,0006 bis 0,0008 mol-% liegend ermittelt. Die Erhöhung der Temperatur steigert den Korrosionsgrad wesentlich, die Wasserstoffkonzentration dagegen hat hierauf wenig Einfluß.  -  Ein Mittel, die Korrosion zu vermeiden, ist die Entschwefelung des Eintragsgutes bzw. der rückgeführten Gase, wobei das erstere sehr kostspielig ist, oder die Verwendung von gegen Schwefel widerstandsfähigen Metallen. Hierbei zeigen hochprozentige Cr—Ni-Legierungen gute Resultate außer bei hohen Temperaturen und für den praktischen Gebrauch ist 18/8 Cr—Ni-Stahl zufrkiedenstellend. Aluminium weist ausgezeichneten Widerstand auf, ist aber für Druckgefäße nicht verwendbar. Es kann jedoch mit gutem Resultat als Überzug auf niedrig legierten Chromstahl verwandt werden und wird durch Sprtzen, Heißtauchen oder Kalorisieren aufgebracht, wobei Spritzen die am wenigsten zufriedenstellende Methode ist. Da trotzdem aus wirtschaflichen Gründen niedrig legierte Chromstähle und Kohlenstoffstähle an kritischen Stellen Verwendung finden müssen, ist die Bildung von Schalen, unvermeidlich; ihre Entfernung geschieht am besten durch chemische Mittel z.B. Salzsäure unter entsprechender Vorsichtsmaßregeln gegen die entstechenden stark giftigen Gase: Schwefelwasserstoff und Schwefeldioxyd.

    Description / Table of Contents: On the protection at a distance given by Flame Sprayed Metallic Coatings on SteelExperiments are described to determine the degree of protection at a distance given by flame sprayed metallic coatings of zinc, aluminum and MG 5 on steel Flame sprayed metallic coatings were applied leaving gaps of various widths. Some of the coatings were covered almost completely with paraffin. Two corrosion tests were used, one by total immersion in natural seawater from the Baltice sea, the other by intermittent immersion in synthetic seawater according to German Specification DIN 50900. The degree of protection at a distance was judged from the results of tensile tests and by visual observation.No essential differences in the distance effects of the various coatings were observed. Protection at a distance also occured when most of the flame spryaed coating was covered with paraffin. The ratio of the areas of protected and protective metals is the essential factor determining the distance effect. Protection at a distance by flame spayed metallic rings was also observed in corrsion fatigue tests.
    Notes: Beschreibung von Versuchen zur Bestimmung der Fernschutzwirkung flammgespritzter Metallschichten aus Zink, Aluminium und Al Mg 5 auf Stahl. Die aufgespritzte Schicht war dabei absichtlich verschieden weit entfernt und teilweise noch zusätzlich zum größten Teil mit Paraffin abgedeckt. Der Korrosionsangriff erfolgte vorwiegend durch natürliches Ostseewasser im Natur-Dauertauchversuch und im Wechseltauchversuch mit künstlichem Meerwasser nach DIN 50900. Die Beurteilung der Fernschutzwirkung erfolgte durch Zugversuche und visuell.Wesentliche Unterschiede im Fernschutzverhalten der einzelnen untersuchten Metalle wurden nicht beobachtet. Der Fernschutz trat auch bei Abdeckung des größten Teiles der aufgespritzen Schicht mit Paraffin ein. Das Flächenverhältnis zwischen schützendem und geschütztem Metall ist für den Eintritt der Fernschutzwirkung sehr wesentlich. Auch bei Korrosionsermüdungsversuchen wurde der Eintritt der Fernschutzwirkung durch aufgespritzte Metallringe festgestellt.
