Share:
- 1Both nitriding and carburizing involve soaking the part in molten salt baths to introduce carbon and nitrogen simultaneously.
- 2Nitriding introduces nitrogen into the surface at sub-critical temperatures and does not require quenching, unlike carburizing.✓
- 3Carburizing is performed at lower temperatures than nitriding and introduces nitrogen into the steel surface.
- 4Nitriding requires rapid quenching in water or oil after heating, while carburizing does not.
Correct answer
Nitriding introduces nitrogen into the surface at sub-critical temperatures and does not require quenching, unlike carburizing.
