Abstract

For components affected by vibration, fretting wear is one of the most common failure types. In this work, the fretting behavior of ATSP-MoS₂ coating was investigated and analyzed in detail. The tested coating only has two fretting states: partial slip regime (PSR) and gross slip regime (GSR). The coefficient of friction (COF) can be maintained at 0.1 when the pv＜1 MPa·m·s^-1, meanwhile the COF and wear rate are significantly affected by the Hertzian contact stress p. The wear mechanism of the coating mainly includes three aspects, the mechanical damage of the original coating, especially the abrasive wear, the densification of surface film, as well as the formation and rupture of blisters on the surface film.
