摘　　要：文章以材料20Cr2Ni4A的齿轮为研究对象。为了提高齿轮塑性抗力和使用寿命,通过渗碳、调质、表面淬硬工序来改善齿面硬度和芯部力学性能,最终获得该齿轮热处理工艺流程和工艺参数。In this paper, the gears made of 20Cr2Ni4A was taken as the object of study. In order to improve the plastic resistance and service life of gears, the hardness of the tooth surface and the mechanical properties of the core were improved. By carburizing,quenching and tempering and surface hardening, the heat treatment process and process parameters were finally obtained.
