Which outcome results when a corrosion-resistant oxide layer is disrupted in stainless steel exposed to concentrated chloride?

A)Pitting corrosion initiates and propagates
B)Improved passivation spontaneously repairs damage
C)Uniform oxidation dominates entirely
D)Galvanic protection shifts cathodic activity

💡 Explanation

Pitting corrosion initiates because disruption exposes bare metal, therefore Ionic Chlorides diffuse within forming tiny anodes via autocatalysis, rather than passivation which would require oxidizing conditions or uniform oxidation impacting the intact resistant layer.
