Description

Surface hardening is a usual treatment to increase the tolerance for fatigue, fretting corrosion, and wear of steel parts such as gears and axles. Typical operation is the induction hardening, in which the surface is heated using a high-frequency AC current and then quenched to form a “hard” layer of martensite on the surface. At the same time, the volume expansion associated with the martensite transformation generates the compressive residual stress, which works to restrain the crack initiation and progression.
