Why it matters
This objective helps connect Enhancement of materials to exam-style questions, flashcards, and revision notes for Enhancement of materials.
Quick student answer
Which of the following is a method of case hardening?
Direct answer
Carburizing is a case hardening process that involves adding carbon to the surface of a steel part.
Key terms
- Quenching: The rapid cooling of a metal, usually by immersion in water or oil, to harden it.
- Carburizing: A case hardening process where carbon is introduced to the surface of steel to increase its hardness.
Common trap
Confusing hardening with tempering: Remember that hardening increases hardness, while tempering reduces brittleness and improves toughness.
