(a) Hydrogen blistering and hydrogen attack

(b) Hydrogen attack and Decarburization

(c) Decarburization and hydrogen embrittlement

(d) Hydrogen attack only

I had been asked this question by my college director while I was bunking the class.

Question is from Eight Forms topic in chapter Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Right option is (b) Hydrogen attack and Decarburization

The best explanation: Hydrogen attack and decarburization are high-temperature processes. Decarburization refers to the removal of carbon from metal, is often produced by moist hydrogen at high temperatures. Hydrogen attack refers to the interaction of hydrogen and metal at high temperatures.
