摘　　要：利用四球实验机研究了纳米铜粒子与二聚酸抗磨剂(T402)复配体系的润滑性能。结果表明:两种添加剂在一定浓度范围内都可以改善基础油的抗磨性能。在一定添加范围内,纳米铜粒子与T402复配体系具有一定的协同作用,采用SEM和XPS分析了磨损表面形貌和元素化学状态,并探讨了润滑机理。Four- ball machine tests were performed to study the tribological behaviors of Cu Nanoparticles and dimer acid, a friction modifier. The results showed that both of these additives can improve anti - wear performances of base oil within a given concentration, and the combine of them engenders the synergistic effect in a fixed dosage. The topography of wear scar was studied with Scanning Electron Microscopy （SEM） and the chemical species in the surface layer were analyzed by X - ray Photoelectron Spectroscopy （XPS）. Their anti -wear action mechanism was thus discussed.
