    Description / Table of Contents: Influence of stress on the sensitivity of an austenitic chromium-nickel steel to stress corrosion crackingThe transcrystalline stress corrosion cracking of a chromium-nickel steel (German designation X 5 CrNi I8 9) in 35 % magnesium chloride solution at 150°C exhibits a well defined limit at the 0.01 %yield stress. In the range of intermediate stresses the stress corrosion resistance increases as the load is increased. This behaviour may be interpreted in terms of the time required for the formation of stable cracks. This mechanism apparently follows the gliding step-repassivation model involving a reduction in height of the gliding steps and the influence of a cathodic protection due to the reduction of the mixed potential.
    Notes: Die transkristallin verlaufende Spannungsrißkorrosion des Stahles X 5 CrNi 18 9 zeigt in 35 %iger Lösung von Magnesiumchlorid bei 150°C eine eindeutige Grenzspannung bei der 401 %Dehnungsgrenze. Im Bereich mittlerer Spannungen nimmt der Widerstand gegen Spannungsrißkorrosion mit steigender Spannung zu. Für dieses Verhalten ist im wesentlichen die Zeit bis zur Ausbildung stabiler Risse verantwortlich, was nach dem Gleitstufen-Repassivierungs-Modell durch Abnahme der Höhe der Gleitstufen und durch die Wirkung eines kathodischen Schutzes infolge der Absenkung des Misch- potentials gedeutet werden kunn.

    Description / Table of Contents: The potential behaviour of the interphase of metallic materials at mild and strong vibratory cavitation IV. Aluminium-base materialsIn continuation of the reports already published in previous issues of this periodical the authors present results obtained with aluminium base materials, and in particular pure aluminium, AlMg 5, AlZnMgCu 1.5 and AlCuMg 2. The aggressive media used were sodium chloride solutions and artifical sea water. The potential shift is rather small, even under moderate cavitation conditions; only at rather high accélérations (up to 65000 g and more) the potential displacement may exceed -500 mV. The copper containing alloys form an exception because their potential is constant in the aerated sodium chloride solution in the range of intensities studied. In cases when the protective layer is destroyed and the potential is shifted to more negative values attention has to be paid to the danger of accelerated corrosion in addition to erosion corrosion.
    Notes: In Fortsetzung der schon in früheren Heften dieser Zeitschrift veröffentlichten Berichte legen die Verf. Ergebnisse vor, die mit Al-Werkstoffen, speziell Reinaluminium, AlMg 5, AlZnMgCu 1,5 und AlCuMg 2 erhalten wurden. Als angreifende Medien dienten Natriumchloridlösungen und künstliches Meerwasser. Die Potentialverschiebung ist ziemlich gering, selbst unter mäßiger Kavitationsbeanspruchung; nur bei ziemlich hohen Beschleunigungen - 65000 g und darüber - kann die Potentialverschiebung -500 mV übersteigen. Die kupferhaltigen Legierungen sind in dieser Hinsicht eine Ausnahme, denn ihr Potential ist im Bereich der verwendeten Intensitäten in belüfteter Natriumchlorid-lösung konstant. In den Fällen, in denen die Schutzschicht zerstört und das Potential nach negativeren Werten verschoben wird, muß zusätzlich zur Erosionskorrosion auch beschleunigte allgemeine Korrosion berücksichtigt werden.

    Description / Table of Contents: Improvement of the resistance to corrosion by superheated steam of Incoly Alloy 800 tube material by surface deformation treatmentSpecimens of Incoloy 800 (%, 45.8 Fe, 31.7 Ni + Co, 20 Cr, low additions of Cu, Mn, Al, Ti, Si), having undergone a surface deformation treatment (rolling, bending, sand blasting, needle peening, emery grinding) were exposed to superheated steam (500 and 1000 hrs, 600 and 620 °C, 1, 70 and 145 atm, 0.03 and 3.5 m/s). The weight loss measured has been evaluated as a function of the surface quality. It has been shown that the corrosion losses are inversely proportional to the degree of deformation, corrosion being reduced by 95-96% at 90% deformation. In this context the bending deformation, sand blasting and needle peening are most efficient, while rolling or emery grinding give rise but to deformations in a very thin surface layer which have no “selfhealing” properties. The composition of the corrosion products depends from the degree of deformation: increasing deformation gives rise to a decrease of the iron content, while the contents of nickel, chromium and manganese are increased; this phenomenon is responsible for the protective effect which is due to the formation of chromium oxide coatings.
    Notes: Proben aus Incoloy 800 (%, 45, 8 Fe, 31,7 Ni + Co, 20 Cr, geringe Zusätze von Cu, Mn, Al, Ti, Si) wurden nach einer Oberflächenverformung - Walzen, Biegen, Sandstrahlen, Nadelstrahlen, Schmirgeln - der Einwirkung von überhitztem Wasserdampf (500 und 1000 h, 600 und 620°C, 1, 70 und 145 atm, 0,03 und 3,5 m/s)ausgesetzt. Der gemessene Gewichtsverlust wurde in Beziehung zum Oberflächenzustand ausgewertet. Es zeigte sich, daß die Korrosionsionsverluste umgekehrt proportional dem Verformungsgrad sind: die Korrosion ist bei 90%iger Verformung der Probe um 95-96% verringert. In dieser Hinsicht sind die Biegeverformung, das Sandstrahlen und das Nadelstrahlen am wirksamsten, während beim Walzen oder Schmirgeln nur eine sehr dünne Oberflächenschicht verformt wird, die dann keine selbstheilenden Eigenschaften besitzt. Die Zusammensetzung der Korrosionsprodukte ist abhängig vom Verformungsgrad: zunehmende Verformung führt zu einer Verringerung des Eisengehalts, während die Gehalte an Nickel, Chrom und Mangan in den Korrosionsprodukten ansteigen. Diese Erscheinung ist ursächlich für den Schutzeffekt, der auf der Bildung von Chromoxidschichten beruht.

    Description / Table of Contents: Untersuchung des Verhaltens von Titan in sauren Lösungen. 2. Verhalten des Makroelements (Titan in belüfteter saurer Lösung) (Titan in entlüfteter saurer Losung)Das elektrochemische Verhalten des Makroelements (Ti - mit und ohne Abschirmung - in entlüfteter saurer Lösung) wurde untersucht mit dem Ziel, Anomalien im Verhalten des Titans in Gegenwart abgeschirmter Flächen zu klären, das nach Literaturberichten gelegentlich an chemischen Apparaten auftritt. Auf der Grundlage der so erhaltenen Ergebnisse bestimmen die Verf. die Bedingungen, welche die Verf. die Bedingungen, welche die Spaltkorrosion begünstigen, wenn Titan der Einwirkung derartiger Lösungen ausgesetzt wird.Aufgrund der experimentellen Ergebnisse konnten die kritischen Bedingungen bezüglich der Stabilisierung des Makroelements in 0,5 m Schwefelsäure in der Nähe der Umgebungstemperatur ermittelt werden, wo das Makroelement nach vollkommener Passivierung strebt; dieses Verhalten konnte aufgrund der Mischpotentialbildung interpretiert werden.
    Notes: The electrochemical behaviour of the macrocouple [titanium (shielded and unshielded) in deaerated acidic solution]/(titanium in aerated acidic solution) has been investigated in order to establish the reasons for the anomalous behaviour of titanium in the presence of shielded areas that has been reported in the literature and is sometimes observed in process equipment, and then to determine the conditions that favour the crevice corrosion of titanium in the same solutionsOn the basis of the experimental results, it has been possible to establish the criticality of stabilization of the macrocouple in 0.5 M H2SO4 at temperatures close to room temperature (in the sense that the macrocouple always tends towards conditions of complete passivity) and to interpret this behaviour on the basis of the theory of mixed potentials.

    Description / Table of Contents: Incubation period and cracking progress during the transcrystalline stress corrosion cracking of austentitic chromium nickel steels in magnesium chloride solutionsA very sensitive measuring method has enabled new details to be brought to light with respect to to the corrosion behavior of an austenitic steel. According to studies on a steel (German designation Werkstoff-Nr,1.4301) the stress corrosion cracking is a process in three stages, it is a creep stage proceeding apparently without perturbation, a period of discontinuous crack growth and finally a period of discontinuous crack growth. The duration of the incubation period which can be experimentally determined depends from the sensitivity of the measuring method; the ture incubation period, however, is always shorter than the experimentally determined value. The incubation period which is determined on the base of specimen elongation is followed by a discontinuous period characterized by crack-growth and subsequent repassivation and finally by a period with continuous crack growth. This behaviour can be interpreted in terms of the glide step-repassivation model.
    Notes: Mit Hilfe einer sehr empfindlichen Meßmethode konnten Einzelheiten über das Korrosionsverhalten eines austenitischen Stahls ermittelt werden, die bisher unbekannt waren. Nach den Untersuchungen an dem Stahl Werkstoff-Nr. 1.4301 handelt es sich bei der Spannungsrißkorrosion um einen in drei Etappen ablaufenden Vorgang, nämlich einen Fließvorgang, der anscheinend ungestört verläuft, eine Periode diskontinuierlichen Rißwachstums und schließlich eine Periode Kontinuierlichen Rißwachstums. Die Dauer der Inkubationszeit, die experimentell erfaßt werden kann, ist abhängig von der Empfindlichkeit der Meßmethodik; die wahre Inkubationsdauer ist immer kürzer als der experimentell bestimmte Wert. Der Inkubationsperiode, die aufgrund der Dehnung bestimmt wird, folgt eine diskontinuierliche Periode, die durch Rißwachstum und anschließende Repassivierung charakterisiert ist; abschließend folgt eine Periode mit kontinuierlichem Rißwachstum. Dieses Verhalten kann mit Hilfe des Gleitstufen-Repassivierungsmodells gedeutet werden.

    Description / Table of Contents: The evaluation of pitting potentials with particular consideration to the galvano-kinetic measuring methodThe galvano-kinetic method offers certain advantages with respect to the galvanostatic measurement. The last generally requires serveral potential-time curves to be determined at various current densities while the galvanokinetic measurement enables the pitting potentials to be determined by one curve only. The superiority of this method clearly appers in the case of stainless steels in chloride solutions containing nitrates as inhibitors: the inhibition which occurs in certain potential ranges may mask the pitting potential during potentio-kinetic method because of the slow potential feed rate enables these potentials to be determined without difficutly.
    Notes: Die galvanokinetische Methode bietet gegenüber galvanostatischen Messungen gewisse Vorteile. Die zuletzt genanntem erfordern im allgemeinen die Aufnahme mehrerer Potential-Zeit-Kurven bei verschiedenen Stromdichten, während die galvanokinetische Messung die Bestimmung des Lochfraßpotentials mit Hilfe einer einzigen Kurve gestattet. Die Überlegenheit dieser Methode zeigt sich deutlich im Falle der nichtrostenden Stähle in chloridlösungen mit Nitraten als Inhibitoren: Die Inhibierung, die in bestimmten Potentialbereichen auftritt, kann das Lochfraßpotential bei potentiokinetischen Messungen „tarnen“, während die galvanokinetische Messung aufgrund des langsamen Potentialvorschubs die Erfassung dieser Potentiale ohne weiteres weiteres ermöglicht.

    Description / Table of Contents: Die Polarisationswiderstandsmethode zur KorrosionsprüfungDie Messung des Polarisationswiderstandes mit Hilfe von Wechselstrom bietet bei der Bestimmung des Korrosionsverlustes gewisse Schwierikgeiten. Trotzdem sind die Wechselstrommethoden von technischem Interesse, da man unter diesen Bedingungen de Korrosionsgeschwindigkeit-Zeit-Kurven leicht aufstellen kann, die Potentialschwankungen leicht zu kompensieren sind und außerdem gewisse Vorteile bezüglich der Gerätekonstruktion offenkunding sind.
    Notes: The measurement of the polarization resistance using AC enables the corrosion losses to be determined with certain difficulties only, Despite that the AC methods are of technical interest because they allow the determination of corrosion rate/time curves without difficulties and enable potentiel fluctuation to be easily compensated; beyond that they offer certain advantages with respect to the construction of the measuring instruments.

    Description / Table of Contents: Properties of the weldable and corrosion resistant steel X 2 CrNiMoN 25 22In view of the limited application of con- ventional CrNiMo steels the authors have investigated potential applications of the above mentioned steel. An optimum com- position would be (%) 0.02 C, 25Cr, 22 Ni, 2 Mo and 0.1 N. The low carbon content is a vital factor and the nickel content must not exceed 22% because higher contents would give rise to very pronounced precipitation. The new steel ist largely resistance to boil- ing nitric acid it is considerably superior to conventional steels, The high break-through potential is indicative of high pitting resist- ance. Improvements are equally remarkable with respect to mecanical properties and weldability
    Notes: Aufgrund der Grenzen fur die Anwendung herkömmlicher CrNiMo-Stahle haben die Verf. Anwendungsmöglichkeiten fiir den obengenannten Stahl erarbeitet. Die opti- male Zusammensetzung betragt etwa (%) 0,02C, 25 Cr, 22 Ni, 2 Mo und O, I N. Der niedrige Kohlenstoffgehalt ist sehr wesentlich und der Nickelgehalt darf 22% nicht übersteigen, denn bei höheren Gehalten kommt es zu ausgeprägten Ausscheidungsvorgängen. Der neue Stahl ist weitgehend beständig gegen interkristalline Korrosion und ist hinsichtlich der Beständigkeit gegen siedende Salpetersäure den herkömmlichen Stahlen beträchtlich überlegen. Das hohe Durchbruchspotential ist ein Indiz fiir hohe Lochfrafibeständigkeit. Die Verbesserungen gegenuber den herkömmlichen Stahlen er- strecken sich auch auf die mechanischen Eigenschaften und die Schweißbarkeit.

    Description / Table of Contents: The corrosion of CuZn alloys in Chloride solutions with potentiostatic polarisationThe intercrystalline corrosion susceptibility of brasses can be studied either by potentiostatic methods in NH4Cl+HCl solutions with polarisation to +80 mV, or - without polarisation - in NH4Cl+HCl+CuSO4 solutions where the potential of +80 mV is attained without external polarisation. Tests carried out with macroelements formed either by brasses having different structures (α, β/α), or identical structure (α) but different zinc contents (21 and 32% respectively) have shown the preferential attack of the β phase at potentials lower than those required for grain boundary dissolution, and the more anodic character of the alloys of higher zinc content.
    Notes: Die Anfälligkeit von CuZn-Legierungen für interkristalline Korrosion kann entweder potentiostatisch untersucht werden, und zwar in NH4Cl+HCl-Lösungen mit Polarisation auf +80 mV, oder - ohne Polarisation - in NH4Cl+HCl+CuSO4-Lösungen, denn dort stellt sich das Potential von +80 mV auch ohne äußere Polarisation ein. Versuche mit Makroelementen aus entweder Messungen verschiedener Struktur (α, β/α) oder gleicher Struktur (α), jedoch verschiedener Zn-Gehalte (21 bzw. 32%) haben gezeigt, daß die β-Phase bevorzugt angegriffen wird, und zwar bei niedrigeren Potentialen als zur Auflösung der Korngrenzen erforderlich sind, und daß die Legierungen höheren Zn-Gehalts stärker anodisch sind.

    Description / Table of Contents: Some question concerning the anodic potentiostatic phase dissolution of heterogeneous alloys.The anodic current-potential curves of bismuth and cadmium and their alloys in 0,1 n oxygen free sulfuric acid solution were measured, using potentionstatic potential control, It is shwon that in the case of these heterogeneous alloys one cannot calculate the rate of anodic dissolution by usual addition of both bismuth and cadmiun polarisation curves.The experimental polarisation curve of the alloy exhibits, instead, in wide potential ranges smaller current densities than it could be assumed from simple summing the single Cd and Bi-anodic curves.An explanation of this phenomenon is proposed based on the observed behaviour of the corresponding model electrodes. Then a possibility of two jointly acting factors is discussed. So may, on one side, the developing passive layer on bismuth act limiting on the anodic dissolutionrate of cadmium by screening partly its grains during polarization, On the other side, must in the course of polarization the progressing anodic dissolution of cadmium also result in the still decreasing surface area, occupied by its crystals.It should be rather obvious, that the first factor can be effective immediately after the bismuth passivation and later on in the whole passive potential range. On the other hand, should the second factor be valid also in the lower potential range, but its role would grow with time of polarization.
    Notes: Die anodischen Stromstärke-Potential-Kurven von Wismut, Cadmium und deren Legierungen in sauerstofffreier 0,1 n Schwefelsäurelösung wurden potentionstatisch untersucht.Es wurde gezeigt, daß im Falle dieser heterogenen Legierungen die anodische Auflösungskinetik durch übliche Summierung der einzelnen Polarisationskuirven von Wismut und Cadmium nicht berechnet werden kann, Dagegen stellt die experimentelle Kurve der Legierung in einem breiten Potentialbereich stets kleinere Stromdichten dar als diejenigen, welche man durch einfache Addition von den Reinmetallkurven erwarten könnte.Eine Aufklärung dieser Tatsache wird in Versuchen mit entsprechenden Modellelektroden gesucht. Es wird dann auf eine Möglichkeit der gleichzeitigen Mitwirkung von zwei Faktoren hingewiesen. Einerseits könen nämlich die Passivierungsvorgänge an der Wismutkomponente einen störenden Einfluß auf die Auflösungsgeschwindigkeit von Cadmium ausüben. Die sich dabei bildende passive Bi2O3-Schicht kann vermutlich die aktiven Cadmiumkristalle teilweise überdecken (beschirmen). Andererseits wird aber auch die wirksame Oberfläche des Cadmiums im Zuge der fortschreitenden anodischen Herauslösung dieses Metalls während der Polarisation immer kleiner. Der erste Faktor dürfte naturgemäß erst im passiven Potentialbereich des Wismuts auftreten und wirksam sein. Der zweite Faktor bereich gültig, sein Einfluß wächst aber erst im Laufe der andauernden Polarisation.

    Description / Table of Contents: Contribution to stress corrosion cracking by liquid ammoniaAccidents experienced in connection with ammonia shipment in the fertilizer industries of the USA for about 15 years were, at least in part, attributable to the deleterious effect of contaminations by air and carbonic acid. In certain cases it is possible to achieve inhibition by addition of water, but in other cases the use of mild steel is being preferred. High strength steels require a thermal treatment, in particular after welding, because corrosion (inter-or transcrystalline) appears preferentially in the weld seam. By contrast to experiences with shipping containers no such accidents have been experienced so far with storage containers.
    Notes: Unfälle in Zusammenhang mit dem Transport von Ammoniak in der Düngemittelindustrie der USA seit etwa 15 Jahren konnten zumindest teilweise der schädigenden Wirkung von Verschmutzungen des Ammoniaks durch luft und Kohlensäure zugeschrieben werden. In manchen Fällen ist es möglich, durch Wasserzusatz eine Inhibierung zu erreichen, in manchen Fällen zieht man jedoch jetzt die Verwendung von Weichstahl als Behälterwerkstoff vor. bei Verwendung von hochfesten stählen ist besonders nach dem Schweißen eine Wärmebehandlung erforderlich, da die Korrosion (inter- order transkristallin) bevorzugt an der Schweißnaht auftritt. Im Gegensatz zu den Erfahrungen mit Transportbehältern sind mit Lagerbehältern keine Unfälle bekannt geworden.

    Description / Table of Contents: Diffusion of hydrogen through titaniumThe diffusion coefficient of hydrogen in titanium determined by an electrochemical method is D24 ° ∼ 7 × 10-12 cm2 /s at a cathodic polarisation of 10 mA/cm2 . The variation of the diffusion coefficient with temperature enables the activation energy to be calculated (6,9 kcal/Mole). The diffusion takes place with intermediary titanium hydride formation. The diffusion is measured using an electrochemical method with a metallic membrane where the hydrogen generated at the one side is ionized, after diffusion at the other side. It is then possible to establish a relation between the ionization current and the diffused quantity, also as a function of time.
    Notes: Der Diffusionskoeffizient von Wasserstoff in Titan, bestimmt mittles einer elektrochemischen methode, betragt bei einer kathodischen Polarisation von 10 mA/cm2 D24 °∼7 × 10-12cm2/s. Aufgrund der Änderung des Diffusionskoeffizienten in Abhangigkeit von der temperatur kann man die Aktivierungsenergie berechnen (6,9 kcal/mol). Bei der Diffusion kommt es zu intermediärer Bildung von Titanhydrd. Die Diffusion wird gemessen mit Hilfe einer elektrochemischen Methode, bei welcher eine Metallmembran als Bimetall-Membran fungiert und der auf der einen Seite der Membran entstandene Wasserstoff nach der Diffusion auf der anderen Seite ionisiert wird. Man kann danach eine Beziehung zwischen dem Ionisationsstrom und der durchdiffundierten Wasserstoffmenge in Abhangigkeit von der Zeit aufstellen.

    Description / Table of Contents: The oxidation of intermetallic zirconium alloys in oxygen and steam at 400°CThe author has studied the oxidation behaviour of some intermetallic zirconium alloys in oxygen and steam. Depending on their behaviour the alloys can be divided into three categories: 1Selective oxidation of alloying elements in the case of the alloys ZrAl3 et ZrSi2Selective oxidation of Zr produced by rearrangement and enrichment of alloying elements in the case of Zr4Sn, ZrCU3 ZrNi, ZrV2 and ZrMo2/3Oxidation control by mixed oxides in the case of ZrNb and ZrTaThe mechanism of the corrosion of ZrAl3 and ZrSi2 in steam is interpreted in terms of the selective attack of Al and Si respectively.
    Notes: Das Oxydationsverhalten von einer Reihe von intermetallischen Zirkoniumlegierungen wurde in Sauerstoff und Wasserdampf untersucht. Die Legierungen konnten aufgrund ihres Verhaltens in drei Gruppen aufgeteilt werden: 1Selektive Oxydation der Legierungselemente bei den Legierungen Zr Al3 und Zr Si.2Eine selektive Zr-Oxydation rief eine Umgruppierung und Anreicherung der Legierungselemente bei Zr4Sn, Zr Cu3, Zr Ni, Zr V2 und Zr Mo2 hervor.3Bei den Legierungen Zr-Nb und Zr-Ta wird der Oxydationsverlauf durch Mischoxyde gesteuert.Der Korrosionsmechanismus der Legierungen Zr Al3 und Zr Si2 in Wasserdampf wird durch selektiven Angriff auf Al und Si erklärt.

    Description / Table of Contents: An optical method for continuously following slow corrosion processesThe method presented here is based on the variation of the optical transmittance and, consequently, can be applied to very thin (some 1000 Å ) metal layers only. Because of the high absorption coefficients of metals it is possible by this method to follow dissolution processes of the order of monoatomic layers. The light source used is a He-Ne-laser. The following applications are described: dissolution rate of chromium in the transpassive range; dissolution of gold in sulfuric acid with additions of hydro chloric acid; photolytic corrosion of titanium.
    Notes: Die hier verwendete Methode beruht auf der Veränderung der optischen Durchlässigkeit und kann infolgedessen nur auf sehr dünne (einige 1000) Metallschichten angewendet werden. Aufgrund der hohen Werte der Absorptionskoeffizinten von Metallen ist es möglich, mit dieser Methode Auflösungsvorgänge in der Größenordnung monomolekularer Schichten zu verfolgen. Als Lichtquelle wird ein He-Ne-Laser verwendet. Beschrieben werden die folgenden Anwendungen: Auflösungsgeschwindigkeit von Chrom im Bereich der Transpassivität;Auflösung von Gold in Schwefelsäure mit HCL Zusatz;photolytische Korrosion von Titan.
