Cyaniding steels with the use of triethanolamine

Cyaniding is widely used in basic engineering for surface strengthening of parts. Triethanolamine is often used as the liquid matter in the process. However, cyaniding is often conducted by adding ammonia into the liquid matter, which creates problems with the utilization of the remaineder of the gas. The addition of other gases (nitrogen, argon, etc.) into ammonia is not appropriate because Get price

Case

Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the case) at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen Get price
