Carburizing of steels
Carburizing is a case hardening process in which carbon diffuses into the surface layer of a steel part at a temperature high … See more Carburization of steel involves heat treatment of the metallic surface using a source of carbon. Carburization can be used to increase the surface hardness of low carbon steel. Early carburization used a direct application of … See more In the past, depending on the carbon source, there were three types of carburizing methods: solid carburizing, liquid carburizing, and gas carburizing. Charcoal, molten salt, and carbon-containing gases … See more WebCarburizing is a case hardening process in which carbon diffuses into the surface layer of a steel part at a temperature high enough to change the steel grain structure. This change enables the steel to absorb carbon. The result is a wear-resistant layer that makes the carburizing an ideal process in the production of strong, safe metals.
