The Significance of the 'Protection Potential' for Fe-Cr Alloys at Room Temperature,

Abstract

The concept of the 'Protection Potential3 (against pit propagation) was introduced by M. Pourbaix et al. during the early 1960's as a result of research related to the pitting behavior of stainless steels and of copper in the presence of aqueous solutions containing chloride. It was suggested that, if the solution does not then contain any oxidizing species (such as oxygen, chromate, copper, etc.), this zero-current potential corresponds to a state of no-oxidation, and this means no corrosion. The purpose of the research reported herein was to apply the suggestion of Pourbaix in an attempt to distinguish between repassivation and deactivation mechanisms for an Fe-12Cr alloy in saline solutions.
