Influence of Prior Electrochemical History on the Propagation of Localized Corrosion

Abstract

It has been shown that in chloride solutions, a binary FeCr alloy containing 16.9% Cr and 0.15% C, may be activated for pitting corrosion by subjecting it to potentials at and above the pitting potential (or rupture potential, E(R)). Once activated, pits will continue to propagate at potentials between E(R) and the protection potential E(P). It also has been shown for this alloy that unless the potential has been raised above the pitting (or rupture) potential, even intentional scratches do not propagate as active pits.
