Anodic Behavior of White Iron Phases in Oxalic Media

Potential-pH diagrams of the iron-oxalic acid and ferric carbide-oxalic acid systems taking into account the equilibrium iron or ferric carbide and ferrous (II) oxalate are plotted. Kinetic investigations of the anodic dissolution of white iron, containing ferritic (99.975% Fe) and cementite (Fe^sub...

Description
Summary:Potential-pH diagrams of the iron-oxalic acid and ferric carbide-oxalic acid systems taking into account the equilibrium iron or ferric carbide and ferrous (II) oxalate are plotted. Kinetic investigations of the anodic dissolution of white iron, containing ferritic (99.975% Fe) and cementite (Fe^sub 3^C) phases, oxalic acid environment evidence that the alloy is passivated due to the formation of a FeC^sub 2^O^sub 4^ polylayer.[PUBLICATION ABSTRACT]
