Pitting and sulphide inclusions in steel
TL;DR: Pits are initiated at sulphide inclusions (usually MnS) in both carbon steels and stainless steels as discussed by the authors, and the propagation of a pit is, in principle, the same in both types of steel and depends upon the formation of a concentration cell in which the pit solution has a higher salt content, a higher acid content and a lower oxygen content than the surrounding bulk of the solution.
Journal ArticleDOI
Review article on the influence of sulphide inclusions on the corrodibility of Fe and steel
TL;DR: In this article, the results are discussed in relation to welding and continuous casting of steel, and the results show that steel composition is of little or no importance for general corrosion but exerts a deciding influence on local corrosion, such as corrosion at welds, crevice corrosion and pitting.
Journal ArticleDOI
On the mechanism of crevice corrosion of stainless Cr steels
Gösta Karlberg,G. Wranglén +1 more
TL;DR: In this article, the mechanism of crevice corrosion of stainless Cr steels in neutral 3%NaCl solution has been studied in a cell constructed for this purpose, and both pH and potential of the steel surface increase as a result of alkali formation (O 2 reduction) during corrosion of the stainless steel in the passive state and thickening of the air-formed oxide film.
Journal ArticleDOI
Cathodic and anodic efficiency losses in chlorate electrolysis
L. Hammar,G. Wranglén +1 more
TL;DR: In this paper, it was shown that the reduction loss is independent of pH between 6·5 and 10·5 if the total hypochlorite concentration is kept constant, inversely proportional to the current density.
Journal ArticleDOI
The “rustless” iron pillar at Delhi
TL;DR: Ghosh et al. as discussed by the authors analyzed the corrosion rate of a 1600-y old forge-welded wrought Fe pillar at Delhi, India and found that the part of the pillar which is below ground is covered by a rust layer, about 1 cm thick, and shows deep pitting.
