Title: Modified low temperature case hardening process
Inventor: WILLIAMS PETER C
IPC: C22C38/00
Filed: 2011-07-06
Abstract: PROBLEM TO BE SOLVED: To improve low temperature gas carburization processes to achieve faster, more economical operation though it can achieve hardened stainless steel products with superior corrosion resistance, and to provide a modified low temperature gas carburization process for case hardening stainless steel and other ferrous-based materials which allows faster carburization than possible in the past and thereby reduces the overall cost of such procedures.SOLUTION: The modified low temperature case hardening processes are concretely a process for enhancing the surface hardness of a workpiece by gas carburization comprising contacting the workpiece with a carburizing gas at an elevated carburizing temperature sufficient to promote diffusion of carbon into the workpiece so as to form a hardened case with a prescribed thickness without the formation of carbide precipitates. The instantaneous rate of carburization is more reduced during the carburization in such a manner that the swift carburization is promoted in the early stage of the carburization, and simultaneously, the formation of carbide precipitates in the latter stage of the carburization is avoided.
