Definitions for "Carbonitriding"
An evelated-temperature process (similar to carburizing) by which a ferrous metal absorbs both carbon and nitrogen into the surface when exposed to an atmosphere high in carbon and nitrogen. The carbon and nitrogen atoms diffuse into the metal to form a high-carbon and high-nitrogen zone near the surface.
A process in which a ferrous alloy is case hardened by first being heated in a gaseous atmosphere of such composition that the alloy absorbs carbon and nitrogen simultaneously, and then being cooled at a rate that will produce desired properties.
A thermochemical method of surface hardening a steel in which the steel is heated into the austenitic region and carbon and nitrogen diffused into the steel surface, following which, the steel is quenched.
