摘　　要：研究了加入纳米铜添加剂的润滑油的摩擦学性能和主要理化性能.在XP-6数控摩擦磨损试验机和四球摩擦试验机上进行了纳米铜的摩擦学性能试验,结果表明,纳米铜对钢-钢摩擦副表现出良好的抗磨减磨性能,与未加添加剂的基础油相比,可使PB值提高34.95%,磨斑直径减少了56.8%,摩擦系数降低39.1%;理化试验表明,加入纳米铜后的基础油仍具有较好的理化特性.The tribological and main physicochemical properties of the Nano-Cu as lubricating additive were analyzed. The tribological characteristics of the Nano-Cu were explored by the XP-6 NC friction and wear test machine and four-ball friction tester. Results indicate that nano-copper exhibits good tribological properties, PB increases 34. 95%, wear diameter decreases 25% averagely, and fiction coefficient ruduces 33.1%. Physicochemical propertie were tested, and the results show that Nano-Cu lubricating oil has good viscosity-temperature property, anti-emulsification property, good corrosion, low pour point, high flash.
