The MM200 friction tester was used to investigate the wear life of FeCrBSi coating prepared by plasma 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 FeCrBSi 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 delamination within the coating was caused by the increasing load.The interfacial delamination of coating was resulted from 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.
