Answer:
The oldest surface-hardening method is carburizing, in which steel is placed at a high temperature for several hours in a carbonaceous environment. The carbon diffuses into the surface of the steel, rendering it harder. Various techniques of carburizing have been developed to increase efficiency and reduce cost.
