1.	Which of the following types of hydrogen damage processes are high-temperature processes?(a) Hydrogen blistering and hydrogen attack(b) Hydrogen attack and Decarburization(c) Decarburization and hydrogen embrittlement(d) Hydrogen attack onlyI 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» 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.
