高频局部表面强化,是用300～400千赫频率范围内的高频电流,通过高频接触器体系(两个接触器和临近导体)直接输入在临近导体下面的需淬火的零件表面,并控制表面的热效应,使表面加热;接着,被加热的表面在毗连的冷的金属物体影响下,使能在马氏体转变温度以下迅速地自行淬火。因为电流集中,
High frequency local surface hardening is accomplished by high frequency current in the frequency range of 300-400 kHz input directly into the surface of the part to be quenched under the adjacent conductors by a high frequency contactor system (two contactors and adjacent conductors) The thermal effect of the surface is controlled to heat the surface; the heated surface is then rapidly self-quenched below the martensitic transformation temperature, under the influence of a contiguous cold metal object. Because of the current concentration,
