Anodic Corrosion of Lead in H[sub 2]SO[sub 4] Solutions

J. J. Lander1951-01-01Journal of The Electrochemical Society

Pure lead was anodized at various constant potentials in sulfuric acid solutions. At potentials below those for formation, a layer of tetragonal is formed near the lead. is formed as an outer layer. The rate of corrosion of Pb was found to increase with increasing temperature and decreasing acid concentration and is g…

CONTACT STRESS AND DEFORMATION IN A THIN ELASTIC LAYER

Margaret Hannah1951-01-01The Quarterly Journal of Mechanics and Applied Mathematics

The rollers used in drafting textile fibres are disk-shaped, the lower one made of steel, the upper with a metal centre and a fairly thin elastic cover. The length over which the rollers are in contact, and the pressure distribution over this length, are factors which affect their performance as drafting agents. The p…

The Kinetics of the Oxidation of Cobalt

Earl A. Gulbransen、Kenneth F. Andrew1951-01-01Journal of The Electrochemical Society

The kinetics of oxidation of cobalt is a complex problem since the metal forms two or more oxides and the metal itself has a phase transition from hexagonal to face‐centered cubic at a temperature between 300° and 500°C. The vacuum microbalance method is used to study the effect of time, temperature, pressure, pretrea…

Über Molybdänblau

Oskar Glemser、Gertrud Lutz1951-01-01Zeitschrift für anorganische und allgemeine Chemie

Abstract Molybdänblau liegt weder eine einzige Verbindung noch eine einheitliche Reduktionsstufe zugrunde. Es hängt vom Ausgangsmaterial, dem angewandten Reduktionsmittel und der Dauer der Einwirkung des Reduktionsmittels ab, welche Verbindung gebildet wird. Die einfachen Molybdänblauarten werden in Blauoxyde und Blau…

Le traînage magnétique

Louis Néel1951-01-01Journal de physique

On montre qu'il convient de distinguer au moins deux espèces de traînages magnétiques : le traînage réversible et le traînage irréversible dont on peut décrire les propriétés de la manière la plus simple, du point de vue formel, en introduisant deux champs magnétiques fictifs de traînage, dépendant du temps et superpo…

Potential-pH Diagram of Zinc and its Applications to the Study of Zinc Corrosion

Paul Delahay、Marcel Pourbaix、Pierre Van Rysselberghe1951-01-01Journal of The Electrochemical Society

On the basis of methods and conventions previously described (1) and using the available thermodynamic and electrochemical data, the potential‐ p H diagram of zinc has been constructed. Derived diagrams showing domains of corrosion, passivity, and passivation in the absence and in the presence of carbon dioxide, bicar…

Les points de transformation des composés définis MnAs, MnBi en relation avec un mécanisme probable d'antiferromagnétisme

Charles Guillaud1951-01-01Journal de physique

On donne et l'on discute les principales propriétés des composés définis MnAs et MnBi qui permettent d'envisager, non pas un point de Curie, mais un point de transformation. Ce dernier pourrait être interprété comme un passage du ferromagnétisme à l'antiferromagnétisme.

The deterioration and breakdown of dielectrics resulting from internal discharges

J.H. Mason1951-01-01Proceedings of the IEE - Part I General

The deterioration of polythene and other dielectrics, when exposed to internal discharges, has been examined under controlled conditions. The discharge-inception voltage and the magnitude and energy of individual discharges have been determined, and the location and number of discharges in voids of different dimension…

Molybdate and Tungstate as Corrosion Inhibitors and the Mechanism of Inhibition

W. D. Robertson1951-01-01Journal of The Electrochemical Society

A comparative study of corrosion inhibition of iron by molybdate, tungstate, chromate, and nitrite was made to evaluate the relative efficiencies of the different ions and to investigate the mechanism of inhibition. It was found that both molybdate and tungstate are efficient inhibitors and comparable in this respect…

Propriétés magnétiques des ferrites

Charles Guillaud1951-01-01Journal de physique

Nous donnons une étude générale des propriétés magnétiques des ferrites simples et mixtes et nous les discutons en vue d'établir les relations qui existent entre ces propriétés et la distribution des ions dans les ferrites à structure de spinelle.

The Zirconia-Yttria System

Pol Duwez、Frank H. Brown、Francis Odell1951-01-01Journal of The Electrochemical Society

The phase relationships in the zirconia‐yttria system have been established up to 2000°C. The addition of 0 to 5 mole per cent yttria lowers the temperature at which zirconia transforms from the tetragonal to the monoclinic form. From 7 to 55 mole per cent yttria is soluble in zirconia and this solid solution is cubic…

The Electrodeposition of Aluminum from Nonaqueous Solutions at Room Temperature

Frank H. Hurley、Thomas P. WIer1951-01-01Journal of The Electrochemical Society

The electrodeposition of aluminum in the form of white or shiny adherent plates on various metals has been accomplished at room temperature. A satisfactory plating solution is prepared by mixing two moles of anhydrous aluminum chloride with 1 mole of ethyl pyridinium bromide, preferably in a dry, oxygen‐free atmospher…

Calculation of Diffusion Penetration Curves for Surface and Grain Boundary Diffusion

J. C. Fisher1951-01-01OpenAlex

Diffusion in solids is known to occur along grain boundaries and over free surfaces more rapidly than through the interiors of crystals. In order to facilitate quantitative investigation of grain boundary and surface diffusion, a mathematical analysis of the problem has been completed, assuming that grain boundary dif…
