How does surface hardening affect the creep resistance of a material?

The brief but intense heat of an electric spark, struck between an electrode and the steel surface, can harden a small volume of material. 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 ... Oct 1, 2007 ... Hard turning induces a thicker plastically deformed zone than grinding, while grinding temperatures penetrate deeper into the subsurface. Apr 22, 2020 ... Case hardening is a material processing method that is used to increase the hardness of the outer surface of a metal. Case hardening results in ...
