• Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question …   Wikipedia

• Induction hardening — is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to… …   Wikipedia
