Definition

A rapid, localized surface hardening process for ferrous components in which alternating electromagnetic fields induce eddy currents that heat a targeted surface layer to a transformation temperature, followed immediately by controlled quenching of that heated zone to form martensite or other hard microstructures while minimizing bulk heating and distortion.
