| 摘 要： | 探讨了纳米铜不同分散工艺和添加量对润滑油摩擦学性能的影响。分别采用超声分散和球磨分散工艺，将3种不同工艺制备的纳米铜材料溶于SF15W／40机油中，在T-11摩擦磨损试验机上进行摩擦学性能试验。结果表明，其中一种纳米铜能够提高基础油的减摩性能，采用超声分散比采用球磨分散的减摩性能好。随着纳米铜浓度的增加抗磨性能有明显的提高，分析认为纳米铜在摩擦表面的沉积有利于提高摩擦学性能。

| Abstract: | The effect of the disperse process and additive concentration of nano-Cu on the tribological properties of lubricant oil was discussed.Three kinds of nano-Cu particles were dispersed in SF 15W/40 lubricant oil by means of ultrasonic disperse and ball-milling disperse process.The wear test was carried out on a T-11 ball-on-plate friction and wear tester made in Poland.The results show that one of the nano-Cu shows better tribological properties,the ultrasonic disperse process shows better friction-reducing properties than the ball-milling disperse process.The anti-wear abilities of the oil are improved with the increasing concentration of nano-Cu.The deposition of nano-Cu on the worn surface contributes to the increasing of the tribological properties. |
