Question

Metals that follow linear oxidation kinetics at low temperatures tend to oxidize catastrophicallyat high temperatures.

(a) True

(b) False

This question was addressed to me during an interview.

This key question is from High Temperature Materials in chapter High Temperature Corrosion of Corrosion Engineering

Answer 1

Right choice is (a) True

To explain I would say: Metals that follows linear oxidation kinetics at low temperature tend to oxidize catastrophically at high temperatures. It is due to the rapid exothermic reactions at the surfaces at high temperatures.
