摘　　要：目的进一步提高碳基固油复合润滑体系的摩擦学性能。方法采用等离子体增强化学气相沉积技术(PECVD)和薗头-萩原(Sonogashira-Hagihara)偶合反应,分别设计制备具有类富勒烯结构的碳基(FLC)涂层和具有层状特征的多孔芳香骨架碳基(LPAF)添加剂。在此基础上,构建由FLC涂层、LPAF添加剂及PAO10基础油组成的三元复合润滑体系,系统考察三元体系的摩擦学行为,并提出潜在的摩擦机制。结果LPAF的层状特性有效降低了界面摩擦,在界面剪切和摩擦热的共同作用下,LPAF由初始的非晶薄片形态通过石墨化转变为圆形类洋葱碳薄片,成为进一步减小复合体系摩擦的关键,使摩擦因数最低降至0.016;此外,LPAF能够对FLC涂层磨损区域进行填补,提升其耐磨损能力,其磨损率低至1.7×10^(–9)mm^(3)/(N·m)。结论绿色环保型LPAF添加剂能够显著提升基于碳基涂层和基础油构建的固p油复合润滑体系的摩擦学性能。The relentless march of scientific and technological advancements has led to a surge in demand for more efficient lubrication technologies.The limitations of conventional single-method lubrication are becoming increasingly apparent,as they fail to fully address the industrial need to reduce friction and wear,extend equipment life spans,and enhance production capabilities.In response to the pressing dual challenges of enhancing lubrication effectiveness and upholding environmental standards,there is a growing impetus to advance the research and development of coating materials and green additives.Addressing the issues of friction and wear at interfaces through establishing a highly efficient carbon-based coating/additive/base oil ternary system,is poised to emerge as a superior option for the future of lubrication and anti-wear technology.In this work,a fullerene-like carbon-based(FLC)coating and a layered porous aromatic framework carbon-based(LPAF)additive were prepared by plasma-enhanced chemical vapor deposition(PECVD)and Sonogashira-Hagihara coupling reaction,respectively.On this basis,a ternary composite lubrication system composed of an FLC coating,LPAF additive and PAO base oil was constructed.The tribological behavior of the ternary system was investigated systematically and the potential friction mechanism was proposed.The LPAF additive was a multi-layer material that was stacked with amorphous carbon monolayers,which made LPAF have good stripping properties and laid a foundation for its good anti-friction and anti-wear properties.Observations indicated that the FLC-PAO system exhibited an average friction coefficient of approximately 0.083,with a corresponding wear rate of around 6.0×10^(-9)mm^(3)/(N·m).The incorporation of 1.0%LPAF into PAO10 base oil significantly reduced the average friction coefficient of the FLC-PAO-LPAF system to about 0.016,while the wear rate was diminished to 1.7×10^(-9)mm^(3)/(N·m).These findings underscored the substantial benefits of LPAF as an additive in enhancing the
