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, ER. Once activated, pits will continue to propagate at potentials between ER and the protection potential EP. 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.
