1.	Carburizing is a case hardening process in which carbon is added to the surface of a metal.(a) True(b) FalseThe question was asked in unit test.Query is from Method of Heat Treatment in section Heat treatment of Metals and Alloys of Casting-Forming-Welding II
Answer» The CORRECT option is (a) True Best explanation: Carburizing is a case hardening process in which carbon is added to the metal surface. In the process of carburizing, when the metal is heated in a container with charcoal, the case becomes very hard and the inside CORE REMAINS soft and tough. Then the metal PART is removed from the furnace for air cooling.
