摘　　要：利用四球摩擦磨损试验机对MoDDP的摩擦学性能进行了考察;使用扫描电子显微镜(SEM)和能量色散X射线分析仪(EDS)分析了磨斑表面微观形貌及元素组成,探讨了MoDDP的润滑作用机理。结果表明:MoDDP具有良好的抗磨减摩和极压性能,392 N载荷下抗磨减摩效果最佳;1%和0.75%分别为油品最佳减摩和最佳抗磨的MoDDP添加量。SEM和EDS分析结果表明,S、P、Mo等MoDDP特征元素参与了摩擦过程,反应生成的含S、P、Mo化合物在提高油品润滑性能方面发挥了重要作用。In this paper,the tribological properties of MoDDP were investigated with four-ball test machine and the micro-morphologies and element contents of wear scar surfaces were analyzed with SEM and EDS.The results of tribological tests indicate that MoDDP possesses excellent antiwear,friction-reducing and extreme pressure properties,especially under the load of 392 N;1% and 0.75% are respectively the best friction reducing addition and best antiwear addition of MoDDP.The results of SEM and EDS analysis show that elements including S,P,Mo have participated in the friction process,and compounds containing elements of S,P,Mo formed in the process have played an important role in improving lubricating properties of oils.
