Oxidation–reduction reactions and hydrogenation of steels of different structures in chloride-acetate solutions in the presence of iron sulfides

Abstract The influence of iron sulfide on the rate of cathodic and anodic processes of steels with ferrite, perlite and ferrite perlite structure was shown. It was established that the hydrogenation and corrosion rate of steels with different structures depends not only its structure, but also the nature of sulfide-containing products of corrosion. The well-known scheme of the influence of hydrogen sulfide on the processes of corrosion and hydrogenation of steel was supplemented by reactions of formation iron sulfides. They can affect the rate of recombination of hydrogen atoms and, respectively, its molation and absorption by metals.
