Abstract | In this paper, WS2-based solid/liquid systems were established successfully by combining pure WS2 films with FCPSO (trifluorinated-propyl and chlorinated-phenyl with methyl terminated silicone oil) and SiCH (silahydrocarbons) space oils, and the tribological performances and mechanisms were investigated. The results showed that the tribological properties of the WS2 film were improved greatly when associated with the SiCH oil, and hence this composite system exhibited a low/stable friction coefficient (<0.08) and a durable wear life (>3 × 106 sliding cycles) both in vacuum and air environments. However, the reverse effect was obtained from the WS2 film/FCPSO system. The selective adsorption of the WS2 crystallographic planes with the specific oils seemed to dominate the tribological performance of the composite systems. The SiCH and FCPSO oils have an affinity for the base and edge planes, respectively, of the WS2 films in their composite systems. The combination of the WS2 base plane with SiCH was more advantageous for the formation of perfect lubricating and transfer films at the friction contact area, resulting in improved friction and wear performances. This result provides a significant way for us to design solid/liquid lubricating systems based on lamellar solid lubricants. |
