_________ is a form of carburization resulting in accelerated localized pitting which occurs in carburizing gases and/or process streams containing carbon and hydrogen. Pits usually form on the surface and may contain soot or graphite dust.
A) Hydrate corrosion
B) Carbide corrosion
C) Spheroidization
D) Metal dusting

Question

Quizplus · Accepted Answer

The given description matches the phenomenon of metal dusting, which occurs in carburizing gases with high carbon and hydrogen content. It results in localized pitting on the surface of the metal, and the pits may contain graphite or soot dust. Hydrate corrosion, carbide corrosion, and spheroidization are not relevant to this description.
