摘要：

The construction of green and friendly solid-liquid lubrication system, especially the composite system without harmful elements such as phosphorus and sulfur, has been a hot research topic in tribology. In this paper, through the friction and wear performance of the prepared TiN-Ag/polyalphaolefin (PAO) composite system, various factors affecting the lubrication behavior of the solid-liquid composite system were deeply explored, including the surface energy of the film, the lubrication state of the composite system, the adsorption energy of the TiN-Ag/PAO system, tribochemical products, etc. The friction reduction mechanism of TiN-Ag/PAO solid-liquid composite system was revealed. In particular, through the characterization of tribochemical products accumulated at the contacting interface, the internal mechanism of PAO degradation to form amorphous carbon was revealed, and the catalytic induction mechanism of Ag and AgO2 in the process of PAO degradation was clarified.
