硼酸酯对ZDDP和氯化石蜡减摩抗磨性能的影响

The Effect of Organic Borate on the Friction reduction and Antiwear Behaviors of Zinc Dialkyldithiophosphate and Chlorinated Paraffin

  • 摘要: 通过摩擦学性能测试和摩擦表面膜成份的x-射线能量色散谱(EDS)分析,研究了硼酸酯同氯化石蜡和二烷基二硫代磷酸锌(ZDDP)相互作用机理。试验结果表明;硼酸酯具有良好的减摩效果。氯化石蜡含量影响其与硼酸醒的相互作用效果。石油磺酸钙用作分散剂使硼酸酯的抗磨性能变差,ZDDP与硼酸酯在摩擦过程中互相竞争金属表面,从而改善硼酸酯的抗磨性,硼酸酯,氯化石蜡,ZDDP之间在减摩抗磨性能方面产生“协同效应。

     

    Abstract: Based on the tribological testing and EDS analysis of the friction surface film,the interaction mechanism of borate, chlorinated paraffin and zinc dialkyldithiophosphate (ZDDP) additives was studied. The results show that organic borate functioned as a friction modifier. The concentration of chlorinated paraffin affected the interaction with borate. Calcium petroleum sulphonate served as dispersing agent worsened the antiwear property of borate. ZDDP and borate had a competitive action on the metal surface in the process of friction. This improved the antiwear property of borate. There existed synergistic effect among organic borate, chlorinated paraffin, and ZDDP.
