Laser quenched groove surface has high wear resistance, and its wear resistance is higher than that of groove by using highfrequencyquenching and chromium plating method.
激光淬火的环槽表面具有良好的耐磨性，比原高频淬火和镀铬工艺处理的耐磨性有较大提高。

For this reason, special inductor and fixture have been designed and the heat treatment problem of the reverse fork has been successfully solved by double highfrequencyquenching.
为此，设计制造了特殊的感应器和工装夹具，采用二次高频淬火工艺解决了该倒挡拨叉的热处理难题。
