Question

Which of the following regions of the seacoast environment shows the effect of the pitting of metals and alloys?

(a) Quiet seawater

(b) High tide region

(c) Low tide region

(d) Splash region

This question was posed to me in class test.

I'm obligated to ask this question of Environments in section Other Environments of Corrosion Engineering

Answer 1

Correct choice is (a) Quiet seawater

For explanation I would say: Pitting is extremely localized corrosion which results in holes or cavities. Quiet seawater in the region of the seacoast environment that shows the effect of the pitting of metals and alloys. An increase in the velocity of a corrosive solution decreases the pitting tendency of a metal.
