1.	Which of the following characteristics of the crevice is a must to act as a corrosion site?(a) It should be wide enough to permit liquid entry(b) It should be narrow enough to maintain a stagnant zone(c) It should be wide enough to avoid a stagnant zone(d) It should be wide enough to permit liquid entry and narrow enough to maintain a stagnant zoneThe question was posed to me by my college director while I was bunking the class.I need to ask this question from Eight Forms topic in portion Eight Forms of Corrosion of Corrosion Engineering
Answer» Right choice is (d) It should be wide enough to permit liquid entry and narrow enough to maintain a stagnant ZONE For explanation I would say: 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.
