为了在边界润滑和混合润滑下获得适当的润滑膜，设计固相和液相之间的界面对于惰性DLC涂层在发动机部件上的应用非常重要。本文制备了nc-(Ti,W)C/a-C(Al)纳米复合涂层。与油品添加剂DMTD相结合，涂层在较宽的载荷范围内表现出优异的边界润滑摩擦性能。通过理论计算以及X射线光电子能谱（XPS）和气相色谱（GC）分析，提出了两阶段减摩机理：低负载下吸附诱导减摩和高负载下摩擦化学反应诱导减摩。我们希望这项工作对于设计适合工业应用的最佳涂料添加剂复合系统具有指导意义。
To achieve an appropriate lubricating film under boundary and mixed lubrication, designing the interface between the solid and liquid phases is very important for the application of inert DLC coating on engine components. In this paper, nanocomposite coatings nc-(Ti,W)C/a-C(Al) were prepared. Combined with the oil additive DMTD, the coatings exhibited excellent boundary-lubricated friction performances under a wide load range. Through the theoretical calculation, as well as X-ray photoelectron spectroscopy (XPS) and gas chromatography (GC) analysis, a two-stage friction decrease mechanism was proposed: adsorption induced friction reduction under low load and tribo-chemical reaction induced friction reduction under high load. We hope this work would be instructive for designing optimum coating-additive composite system for industry applications.
