On the effect of nickel on the corrosion-electrochemical behavior of iron-nickel alloys

  • A. G. Tyurin


The pH-potential diagram of the Ni−H2O system is refined, and similar diagrams of the Fe−Ni- and X18H10 alloy-H2O systems are constructed for a temperature of 25°C. It is shown that nickel may enter into a mixed, magnetite-base spinel (Fe1-x Nix)Fe2O4 (in the case of iron-nickel alloys) or into an iron-chromite base spinel (Fe1-x Nix)(Cr2-y Fey)O4 (iron-chromium-nickel alloys), thus participating in the passivation of alloys.
