Which outcome results when chloride ion concentration increases sharply near stainless-steel?

💡 Explanation

Increased chloride concentration induces pitting corrosion, due to a breakdown of the passive layer. Crevice Corrosion occurs, because the depassivation of the metal surface accelerates when chlorides accumulate; therefore, localized anode dissolution increases, rather than the metal passivating as galvanic couplings require oxidizing agents.
