摘要: 合成了有机钼化合物——二烷基二硫代氨基甲酸钼(MoDTC),并确定主要官能团及元素含量。采用热重分析仪测试了其热稳定性能;采用四球摩擦磨损机评价了其在锂基润滑脂中的摩擦学性能,并与二硫化钼(MoS2)进行对比研究。结果表明:MoDTC具有优良的热稳定性能;载荷为392 N时,MoDTC添加量为3.0%时达到最佳减摩作用,比基础脂平均摩擦因数降低40.2%,添加量为2.0%时到达最佳抗磨作用,比基础脂钢球磨斑直径减小29.8%。
Abstract: he organic molybdenum compound, molybdenum dialkydithiocarbamate (MoDTC), was prepared. The functional group and element content of the compound was determined. The thermal stability was tested by TG-DSC. Its tribological properties in lithium base grease were evaluated by four-ball friction tester and compared with MoS2. The results show that MoDTC possesses a good thermal stability, the physicochemical property of the lithium base adding MoDTC grease is unchanged. Compared with the blank lithium base grease, at 392 N loading, the best anti-friction effect is achieved at 3.0% of MoDTC in grease, the average friction coefficient could reduce by 40.2%, and the mass fraction of MoDTC in grease is 2.0%, when the wear scar diameter is reduced by 29.8%.
