摘要
纳米铜润滑油添加剂具有优异的减摩、抗磨性能从而展现出了广阔的应用前景,然而,纳米铜的表面能较高,纳米铜颗粒间存在较大的吸引力易形成块状聚集体,严重影响了纳米铜润滑油添加剂在工程中的应用,因而解决纳米铜在润滑油中的分散性变得日益迫切。总结了提高纳米铜在润滑油中分散稳定性的方法,阐述了不同分散处理方法的作用机理及其优缺点,提出了纳米铜润滑油添加剂的分散稳定性研究中存在的问题及未来发展的研究方向。
Nano copper powders are used widely on industry due to its excellent antifriction and anti- wear performance. However, copper nanoparticles are formed easily to aggregate due to its high sur- face energy and attraction, which affects seriously in their engineering application. Therefore, it is ur- gent to improve the dispersibility of nano copper powders. The methods of improving nano copper dis- persion stability in the lubricating oil were summarized. In addition, the mechanism of dispersion with different processing methods and their advantages and disadvantages were described. The existing problems and development direction of nano copper powders as lubricant additives are finally pointed out.
