Of gears, various surface-hardening treatments have been proposed. These include such widely used processes as carburizing, nitriding and carbonitriding, and also induc-tionhardening. Induction hardening involves rapid heating of the gear tooth surface by a high-frequency electromagnetic field, inducing eddy currents and heat generation ... Fetch Doc

Carbonitriding - Wikipedia
Carbonitriding is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear.. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip, increasing the hardness and modulus near the surface. ... Read Article

Carburizing - Wikipedia
Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. ... Read Article
