| 摘 要： | 本对合成的一种应用于水-乙二醇液压液的极压抗磨添加剂二聚酸钾进行了润滑性能测试和抗磨作用机理研究．四球实验表明，二聚酸钾的水溶性能和抗磨性能优于水溶性改性ZDDP和Lubrizol5642，以二聚酸钾作为极压抗磨添加剂的水-乙二醇液压液KGY的润滑性能与N46抗磨液压油相当。钢球磨斑表面元素EDS分析表明，在极压条件下，二聚酸钾与摩擦表面发生某种摩擦化学反应，形成了一层有机类抗磨膜。

| Abstract: | The lubricity and anti-wear mechanism of dimer acid potassium-an extreme pressure (EP) additive of water-glycol hydraulic fluid were described in this paper. Four-ball machine tests showed that water-solubility and lubricity of dimer acid potassium are better than water-soluble ZDDP and Lubrizol 5642, also showed that lubricity of water-glycol hydraulic fluid KGY in which dimer acid potassium is added as extreme pressure additive is equal to N46 anti-wear hydraulic oil. EDS analysis of wear scar showed that dimer acid potassium might react with rub surface and form an organic anti-wear film on extreme pressure condition. |
