The Frictional Characteristic of Sputtered MoS2Films under Grease Lubrication

in view of the sputtered MoS2 films are usually used in dry friction, the frictionalcharacteristic of the sputtered MoS2 films under grease lubrication, especially under boundarylubrication, has not been widely investigated. In order to improve the wear-resistance of hollowcylindrical roller bearing, the sputtering technology and the frictional characteristic of MoS2 filmsunderhigh-speed lithium grease lubrication were investigated with ball-dise tester. The resultsshown that sputtered MoS2 films possesses excellent frictional characteristic under the testingconditions. In addition, the chemical states and distribution of elements depth, the thickness ofsputtered MoS2 films were analyzed using X-ray photoelectron spectroscopy (XPS). The influenceof sputtered parameters to MoS2 films were also analysed , the experimental basis to obtain excellentMoS2 films was provided.
