摘要：

In the present work, WS2-MoS2 nanocomposite films were sputtered, based on which solid/liquid-lubrication systems were realized by combining the WS2-MoS2 films with space oils including MACs (multialkylated cyclopentanes) and CPSO (chlorinated-phenyl with methyl-terminated silicone oil). The tribological behaviors of the solid/liquid systems were investigated in vacuum. It was revealed that in comparison to pure WS2 film, the WS2-MoS2 composite film exhibited an enhanced tribological performance. Moreover, our results identified that the WS2-MoS2/MACs system integrated better the advantages of the solid and liquid lubrications and thereby a synergistic lubricating effect was generated. A tribological model was established to explain the synergistic lubricating mechanism. (C) 2016 Elsevier Ltd. All rights reserved.
