Abstract  

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.
