摘　　要：在四球试验机上研究了高温抗氧剂二乙基己基二硫代磷酸铜、二烷基二硫代磷酸铜与抗磨添加剂二烷基二硫代磷酸氧钼复配体系的抗磨减摩性能。结果表明 ,两种有机铜添加剂具有良好的高温抗氧化性能 ,同时本身也具有一定的抗磨减摩性能。当有机铜的添加量较低时 ,有机铜抗氧剂与二烷基二硫代磷酸钼复配体系具有一定的协同抗磨性。采用SEM对磨斑表面的形貌和表面膜的元素组成进行了分析 。Four ball machine tests were performed to study the synergetic effects of copper diethylhexyl dithiophosphate and copper dialkydithiophosphate combining with oxymolybdenum dialkyldithiophosphate The results showed that two kinds of organic copper additives have excellent property of high temperature oxidation resistance Furthermore, they also have certain properties of antiwear and friction resistance From the results of synergetic effects, when the quantities of organic copper oxidation inhibitor were lower, the synergetic effects may be improved The interaction of additives was also studied through SEM analysis
