Bonded flake MoS2 solid lubricant coating: An effective protection against fretting wear

다국어 초록 (Multilingual Abstract)

The multiple advantages of flake MoS2 are of great significance for improving the fretting wear resistanceof bonded solid lubricant coating. Herein, the coating was constructed with liquid-phase exfoliated flakeMoS2 as lubricating filler and epoxy resin as binder. The tangential fretting characteristics for the contactof AISI 52,100 steel ball against the as-prepared coating on the AISI 1045 steel were investigated underthree displacement amplitude. Results show that the average friction coefficient and wear rate of thecoating with flake MoS2 maximumly reduce by 45.5% and 89.8% than those with bulk MoS2. Moreover,the fretting regime is regulated by the coatings with different composition and performance. Such excellentanti-fretting features depend on: (a) the intrinsic shearing properties of flake MoS2; (b) the repairingeffect on the worn area; (c) the formation of uniform transfer film.
