Which of the following characteristics of the crevice is a must to act as a corrosion site? Correct Answer It should be wide enough to permit liquid entry and narrow enough to maintain a stagnant zone

Crevice is a small volume region formed between the interface of metal and gaskets. It acts as a corrosion site if is wide enough to permit liquid entry and narrow enough to maintain a stagnant zone.
