摘　　要：为提升高强化柴油机润滑油的润滑性能,将纳米蛇纹石粉末与极压抗磨剂ZDDP和有机钼减摩剂MoDTC相互复配,采用环块式摩擦试验机研究不同添加剂之间的协同润滑性能,分析摩擦因数、磨损量以及摩擦产物组成等受添加剂组成的影响规律。结果表明:蛇纹石粉末与MoDTC和ZDDP复配能够降低润滑油的摩擦因数与磨损量,并减少摩擦表面划痕;蛇纹石粉末在摩擦副表面形成摩擦自修复涂层,提高摩擦表面硬度和抗磨性能;蛇纹石粉末与MoDTC和ZDDP复配时,蛇纹石粉末促进了MoS_(2)在摩擦表面的生成,进一步降低了摩擦因数,表明蛇纹石粉末与MoDTC和ZDDP起到协同减摩的作用。In order to improve the lubricating performance of highly intensified diesel engine oil,nano serpentine powder,anti-wear additive ZDDP and friction reduction additive MoDTC were mixed to analyze the syngergistic lubricating performance on the ring-block friction test rig.The influence of additives composition on friction coefficient,wear and chemical composition of friction products was discussed.Results indicate that the mixture of serpentine powder,MoDTC and ZDDP can reduce the friction coefficient and wear of lubricant,as well as the wear scar on friction surface.The serpentine powder produce self-restore layer on the friction surface,which improve the surface hardness and anti-wear performance.When serpentine powder is compounded with MoDTC and ZDDP,the serpentine powder promotes the formation of MoS_(2) on the friction surface and further reduces the friction coefficient,which indicates that serpentine powder,MoDTC and ZDDP play a synergistic role in reducing friction.
