摘　　要：通过分析渗碳淬火零件在磨削加工过程中产生的裂纹形态,并结合材料热处理相变理论,分析了磨削以及摩擦裂纹出现的原因。结果表明:裂纹的产生与剧烈摩擦有关,也与摩擦热形成的二次淬火有关。By the analysis of crack form appearing in the carburizing and quenching parts during the process of abrasive maching, and combining with material heat treatment phase change theory, the reasons for the appearance of grinding cracks and friction crack were analyzed. The results show that the appearance of the crack is associated with severe friction, and also associated with the secondary quenching caused by friction heating.

关 键 词：磨削裂纹 摩擦裂纹 二次淬火
