利用弹性接触理论、电镜及光弹应力分析，研究了金属材料在两体磨损工况下的剥层磨损。结果表明，亚表层裂纹形成在高应力区（０≤ｚ≤０．１ａ）和低应力区（ｚ≥０．５ａ）之间。主裂纹在交变的σｘ和τｚｘ作用下沿水平方向扩展，分叉裂纹在τｍａｘ作用下沿３７°角方向扩展，提高材料的屈服强度和裂纹扩展功可显著地提高材料的耐磨性。
Using elastic contact theory, electron microscopy and photoelastic stress analysis, the wear and tear of metal material under two-body wear condition was studied. The results show that sub-surface cracks are formed between the high-stress zone (0≤z≤0.1a) and the low-stress zone (z≥0.5a). The main crack propagates in the horizontal direction under the alternating σx and τzx. The bifurcation crack propagates in the direction of τmax by 37 °. The yield strength and crack extension work of the material can significantly improve the wear resistance of the material.
