【Abstract】 In this paper the boronizing for 65Mn steel bearing pins and 200 hour simulated comparative test with chains of GCr15 steel bearing pins by normal heat treating were introduced.And the wear mechanism and surface morphology were analysed.The result showed that the hinge friction pair composed with boronized bearing pin and 20CrMnMo steel carbonitrided bush is possesses high wear resistance and long service life.更多还原
