Abstract
In acidic chloride-containing solution, the passive film formed at ope n circuit becomes unstable over a certain period, as revealed by subse quent potentiostatic electrochemical noise measurements, showing speci fic current peaks. A hypothesis is made about the possible influence o f a salt layer forming on pit walls during both the propagation and re passivation of unstable pits.
