主　　题：lubricating film metal matrix self‐lubricating composite tribological behavior binary solid lubricants X‐ray photoelectron spectroscopy(XPS) 

摘      要：The aim of this study is to fabricate the nanocomposite with low friction and high wear resistance using binary solid lubricant *** microstructure and tribological performance of the nanocomposite are evaluated,and the composition and film thickness of the lubricating film are observed and analyzed by scanning electron microscopy(SEM)and X‐ray photoelectron spectroscopy(XPS).The nanocomposite exhibited improved tribological properties with a friction coefficient as low as 0.12 and a low wear rate of 2.17×10^(-6) mm^(3)/(N∙m)in high‐purity nitrogen *** sliding speed can increase lubricating film thickness,and the thickest lubricating film is approximately 125 *** the film thickness of the lubricating film exceeded 90 nm,the friction coefficient curves became *** compared with WS_(2),MoS_(2) can be more effective in forming the transfer layer on the worn surfaces at the initial stage of the tribological process.
