石墨烯油润滑添加剂的减摩抗磨性能

Friction-reducing and Antiwear Behavior of Graphene Oil Lubricating Additives

采用多功能往复摩擦磨损试验机考察了石墨烯的减摩抗磨性能,通过三维形貌测量仪、扫描电子显微镜(Scanning Electron Microscopy,SEM)等手段,分析了磨损表面的形貌,初步探讨了石墨烯的润滑机理。结果表明:在试验所选载荷、频率条件下,石墨烯较液体石蜡的减摩抗磨性能有明显改善,但试验条件不同,改善程度也不同;液体石蜡和石墨烯的磨损机理均为磨粒磨损,试验条件可以改变液体石蜡和石墨烯的润滑状态,减轻其磨损程度,但不能改变其磨损机理。

The friction-reducing and antiwear behavior of Graphene is studied by multi-functional reciprocating friction and wear tester,the morphology of wear surface is investigated by 3D surface profile tester and Scanning Electron Microscopy( SEM),and the lubricating mechanism is discussed.The results indicate that,under the test load and frequency,the friction-reducing and antiwear behavior of graphene improves obviously compared with paraffin oil while test conditions are different,improvement is different.Wear mechanism of both paraffin oil and graphene is of particles wear,the test conditions can change the lubricating properties of paraffin oil and graphene,reduce the wear degree,but cannot change the wear mechanism.
