Description

Induction hardening is a well established technique to improve the resistance of components like bearings, gears, rolls etc. against loading and to protect the surface against wear. The hardening process is performed by inductive heating of the near-surface region above the austenising temperature and subsequent water cooling. This normally leads to a martensitic microstructure near the surface with suitable hardness and strength which is separated by a transition zone from the less hard but more tough base material. The hardening depth is defined as the distance from surface where the hardness drops below a given level defined by application dependent standards.

Nondestructive Determination of Hardening Depth in Induction Hardened Components by Ultrasonic Backscattering
