Salt Bath Processes

May 11th, 2015 by admin

Salt bath nitriding is a thermochemical process in which nitrogen and carbon are diffused simultaneously into the surface of the material. The high concentration of nitrogen chemically combines with iron and other nitride forming elements to produce an outer layer of epsilon iron nitride (Fe3N) which is thin, hard and ductile. This layer is also known as the compound zone which has increased surface hardness to enhance anti-galling characteristics and lowers the coefficient of friction and functions as a solid film lubricant by providing a non-metallic interface between mating surfaces.
