An induction heating process for hardening a metal insert retained in a recess formed in a second component comprises the steps of fitting the insert in place within the recess by an interference fit, machining the interior surface of the insert, locating an induction heater adjacent the surface of the insert to be hardened, the heating element being spaced from the metal surface a predetermined distance, and energizing the heating element from the high frequency electrical power source for an extremely brief period.
