Abstract
The fretting wear-resistant properties of ion-sulphuration+shot-peening and shot-peening+ion-sulphuration duplex-treated coatings on 1045 steel substr ate were investigated. The results show that the fretting wear-resistance o f shot-peening+ion-sulphuration coating was better than that of the ion-sul phuration+shot-peening coating. The fretting wear process of the duplex-tre ated coatings in the gross slip regime could be described as the sulphurati on coatings playing an important lubricating role in the incubation period. Then a series of changes took place continuously and alternatively on the contact surfaces. including adhesion, material transfer, oxidation, delamin ation of the oxide layer and degradation. In the last stage, the trapping, pulverization and elimination of debris restrained the adhesion between the contact surfaces and led to a decrease in the friction coefficient.
