Induction Hardening
It is a hardening process where no distortion occurs, and component areas can be hardened selectively according to the requirement. The depth of hardening can be varied, and consistent hardening is achieved. The main advantage of induction heating is that the duration of the process is extremely short due to rapid generation of heat. Components are placed within an electrical coil through which alternating currents is passed. The parts are energized and heated. The heating rate and depth is controlled by changing frequency and amperes. High frequency induction heating involves heating at a high frequency in order to obtain recommended mechanical properties.
