【摘要】 考察了在聚醚 (SDM 0 2C)中分别加入不同质量分数的HL 343与国际品牌Hitec 343、Mobil 2 5 2三种复剂的极压抗磨性 ,初步探讨了添加剂的作用机理。结果表明 ,国产的HL - 343复剂最大无卡咬负荷较高 ,低载长磨磨斑小、痕迹轻 ,主要原因是由于复剂在摩擦中游离出的活性磷元素生成了抗剪切强度很低的薄膜 ,减少了摩擦磨损 ;HL 343综合抗磨性能优于两种进口高性能添加剂Hitec 343和Mobil 2 5 2 ,HL 343复剂完全可以取代进口同类产品。更多还原

【Abstract】 Performance of extreme pressure and anti-wear of HL-343 and international reputed Hitec-343,Mobil-252 respective adding different quality percentage in polyether SDM-02C were investigated,the action mechanism of additive agent was researched.The results indicate that P B value and P D value of mixed agent made in China are higher,the wear scar is small in low load and long-time wear.The main reason was analyzed that living-P,dissolving from the mixed additive agent under friction,formed the film of the low resistance shear strength,so reduced friction and wear.The experiments show that comprehensive anti-wear performance of HL-343 is better than that of Hitec-343 and Mobil-252,meanwhile HL-343 can instead of import same production completely.更多还原
