摘　　要：利用AES和^(31)P NMR对MoDDP(二烷基二硫代磷酸硫化氧钼)与ZDDP(二烷基二硫代磷酸锌)的相互作用进行了研究,并在四球机上考察了两剂复合对润滑油摩擦磨损性能的影响。结果表明,MoDDP与ZDDP复合,其分子间可有烷基和/或烷氧基的交换,并且ZDDP的存在,可使MoDDP和/或其分解产物中的钼原子更易进入到表面膜中。The interaction between sulfurized oxymolybdenum dialkyldithiophate (MoDDP) and zinc dialkyldithiophate (ZDDP) was studied through AES and ^(31)P NMR analysis, and the effect of these 2 additives used in combination on lube oil antiwear the friction properties was inverstigated by a four-ball machine. The results show that the exchange of alkyl and/oralkoxyl groups between MoDDP and ZDDP molecules may exsist and, in the presence of ZDDP, the molybdenum atom in MoDDP and/or its decomposed products may easily come to the surface film.
