摘    要:采用二氧化碳超临界干燥技术制备了粒径为10 ̄20nm的硼酸铜颗粒,并测定了其用作润滑油添加剂的摩擦学性能,结果表明,纳米硼酸铜使500SN基础油润滑下的摩擦系数略有增大,并使其抗磨及承载能力提高,其最佳添加量为0.70% ̄1.10%,纳米硼酸铜颗粒在摩擦表面发生了摩擦化学反应,生成了由B2O3及FeB等组成的表面保护膜,润滑油抗磨性能的提高是纳米硼酸铜粒在摩擦表面的沉积及其摩擦化学产物作用的结果。

关 键 词:纳米颗粒  硼酸铜  摩擦学性能  润滑油添加剂  制备

Abstract:Nanometer copper borate with a particle size of about 10~20 nm was prepared using carbon dioxide supercritical dry technique. The tribological properties of 500 SN oil containing nanometer copper borate were investigated with a four ball machine and a block on ring friction and wear tester. The morphology and chemical features of the wear scar were analyzed by means of SEM and XPS. As the results, the load carrying capacity and antiwear ability of the base stock were increased by the additive. The friction coefficient, however, was slightly increased by addition of the additive in the base stock. XPS analysis of the wear scar indicates that B 2O 3 and FeB were formed on the rubbing surface, which provides the oil with higher load carrying capacity and better antiwear ability.
Keywords:carbon dioxide  supercritical fluid drying  nanometer particle  copper borate  tribological properties
