How can the cost-effectiveness of surface hardening be improved?

Apr 22, 2020 ... Case hardening is a material processing method used to increase the hardness of the outer surface of a metal. Case hardening results in a very ... The brief but intense heat of an electric spark, struck between an electrode and the steel surface, can harden a small volume of material. Jan 14, 2025 ... Surface hardening involves hardening the material on the outside faces of a part, leaving the inside at the material's natural hardness level. Apr 16, 2015 ... TRU-SPARK compound works quickly, hardening to a uniform depth.

Greatly increased scratch-resistance thanks to surface hardening. TEGIMENT ... The term is now used to refer to all materials with a hardened surface. Nitriding. Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas ... Induction hardening. The steel part is heated to a high temperature by using an alternating magnetic field, after which the steel is immediately quenched. The ... In many applications only the surface of a steel part is subjected to high stresses. As a result, only the surface needs to be hardened. Such surface hardening ...
