摘　　要：利用模拟球磨机工矿条件的高能冲击磨损实验装置研究了高能冲击磨损中材料的几种磨损机制。高能冲击磨损过程中表层材料不仅由于剧烈的塑性变形和切削造成磨损，而且还因为产生了独特的表层和亚表层的白层组织，在冲击过程中易于诱发产生裂纹，从而加剧材料的磨损流失。The wear mechanisms of materials in impact wear with high energy were investigated in the paper by using a tester simulating the conditions of mills. In impact wear processes the materials are worn away not only by severe plastic deformation and cutting,but also by the generation of white-etching layers in both surface and subsurface. Cracks are very easy to be produced in whiteetching layers during impact wear process.
