1.	Which of the following metals will depend on the oxide layer for their corrosion resistance?(a) Titanium and stainless steels(b) Titanium, stainless steels, and aluminum and its alloys(c) Aluminum and its alloys(d) Aluminum and its alloy and titaniumThis question was posed to me at a job interview.This key question is from Materials in section Materials of Corrosion Engineering
Answer» Correct CHOICE is (b) Titanium, stainless STEELS, and aluminum and its alloys To EXPLAIN I would say: Corrosion resistance of the metal is the ability of a metal to withstand the effect of a corrosive environment. Titanium, stainless steel, and aluminum and its alloys will RESIST the corrosive environment with the formation of their oxide LAYER.
