A comparative study on fretting wear-resistant properties of ion-plated TiN and magnetron-sputtered MoS2 coatings

This paper studied the fretting properties and mechanism of TiN and MoS2 co atings on 1045 steel. The results showed that the fretting-resistant proper ty of ion-plated TiN coating is obviously better than that of magnetron-spu ttered MoS2 coating on SRV fretting tests. Under the given test parameters (normal load 10 N, slip amplitude 100 mu m and frequency 10 Hz), the fretti ng wear mechanism of TiN coating is particle detachment through the propaga tion and fracture of fine microcracks on surface, and the fretting wear mec hanism of MoS2 coating showed its damage process by degradation and abrasio n of materials.
