| 摘 要： | 本文在四球机上研究了四异丙基硫代过氧二磷酸酯对二异丙基二硫代磷酸硫化氧钼摩擦磨损性能的影响。发现硫代过氧二磷酸酯(TPDP)对硫磷酸硫化氧钼(MoDDP)的抗磨减摩性能有协同作用。俄歇电子能谱(AES)分析的结果表明,TPDP的存在,能提高表面膜中Mo、S的含量,并给出一种可能的作用途径。

| Abstract: | In this paper di-(iso-propyl) sulfurized oxymolybdenumdithioposphate(MoDDP) and tetra-(iso-propyl) thioperoxydiphospbate(TPDP) are synthesized and purified. The function of TPDP has been studied on the four-ball machine. A synergistic effect of TPDP on MoDDP's reducing wear and friction properties is observed. The results of surface analysis (AES) show that the presence of TPDP can increase the percentage of Mo and S in surface film. A possible mechanism of interaction between MoDDP and TPDP on surface is suggested. |
