摘　　要：在MMW-1四球机上研究了由粒径小于50nm的铜粉与清净分散剂制成的浓缩液加入HJ20润滑油后的摩擦磨损性能,结果表明由该纳米铜粉形成的浓缩液能够提高和改善HJ20润滑油的耐磨和极压性能.研究了纳米铜粉浓缩液的最佳加入量,其减摩抗磨机理与纳米颗粒独特的物理化学性质有关.The tribological properties of HJ20 oil added with nano copper powders(diamerter is 10-50 nm) were tested on the MMW-1 friction and wear tester. The results showed that nano copper powders could improve the extreme pressure and antiwear performance of lubricating oil. The optimal concentration of the nano copper powders are studied and friction reducing mechanism is due to its unique physical and chemical characteristics.
