摘　　要：为提高内燃机润滑油的综合性能和延长在用润滑油的使用寿命,提出一种KM型添加剂,主要通过摩擦磨损试验方法验证其润滑特性。将KM型添加剂加入SL 15W-50润滑油中,运用UMT-TriboLab多功能摩擦磨损试验机进行四球式、旋转盘-销式和往复板-销式的钢-钢摩擦副的对比性摩擦学性能试验。同时,利用三维轮廓仪和电子显微镜进行摩擦形貌分析,并使用高精度电子天平测量试验件的质量损失。试验结果表明:KM型添加剂具有良好的自修复性,能有效减少各钢-钢摩擦副的摩擦磨损,提升润滑油的减磨抗磨性能;对于在用润滑油,加入该KM型添加剂之后,其减磨抗磨性能更佳。A new KM additive is proposed to improve the comprehensive performance of lubricating oil of internal combustion engines and to prolong the service life of lubricating oil.Its lubrication performances are verified by the friction and wear tests,where KM additives is put into SL 15 W-50 lubricating oil,and the contrastive tribological property tests of four-ball,rotary plate-pin and reciprocating plate-pin for steel-steel pair are carried out with UMT-Tribolab multi-function friction and wear tester.At the same time,the morphology of friction is analyzed with a 3 D contourgraph and an electron microscope,and the mass loss of test pieces is measured by high precision electronic scale.The test results show that KM additive has good self-repairing ability which can effectively reduce the friction and the wear of steel-steel pairs and improve the anti-wear property of lubricating oil.The anti-wear property of the lubricating oil is much better after the additive is added.
