在MM200摩擦磨损试验机上对高速电弧喷涂3Cr13涂层进行了干摩擦条件下的磨损寿命试验, 通过恒定应力加速模型分别建立了载荷、涂层厚度、摩擦副转速与3Cr13涂层磨损寿命的关系图, 并采用多元回归分析建立了预测3Cr13涂层磨损寿命的模型, 对影响因素进行了相关度分析. 结果表明：载荷的增大引起涂层内分层失效, 涂层厚度的减小则引起涂层整层剥落, 摩擦副的转速主要影响摩擦副间的犁沟和微切削程度. 影响磨损寿命大小的因素依次顺序为: 涂层厚度、载荷和摩擦副转速.
The MM200 friction tester was used to investigate the wear life of 3Cr13 coating prepared by high velocity arc spraying technique under dry friction. By use of constant–stress accelerated model, the relationship curves between the wear life and the three condition factors (load, coating thickness, rotational speed) were established respectively. The preliminary model of the wear life prediction of 3Cr13 coating was
constituted by multiple regression analysis, and correlation analysis of the influencing factors were carried
out at the same time. The results indicated that the cohesive delamination of coating was caused by the
increasing load. The adhesive delamination of coating was a result of decreasing of coating thickness. The
degree of furrow and micro–cutting was determined by rotational speed. The plain sequence of factors,
affecting wear life of the coating was the coating thickness, load, rotational speed.
