摘要
用四球摩擦磨损试验机考察了环烷酸混合稀土、环烷酸亚锡及它们的复配物添加在26#白油中的摩擦学性能,并用俄歇尔电子能谱研究了磨斑表面边界膜的化学组成。结果表明:环烷酸亚锡和环烷酸稀土在抗磨性能和减摩性能方面均存在明显的协同效应,其复配物具有比ZDDP更好的抗磨减摩性能,有望作为新型的高效多功能润滑添加剂在工业实际中得到应用,复配物在摩擦表面形成的含稀土元素和锡元素的边界润滑膜是其具有良好摩擦学性能的主要原因。
The tribological behaviors of mixed rare-earth naphthenate (REN), stannous naphthenate (SN) and their complex as lubricant additives in VG26 white oil were evaluated with a four-ball friction and wear tester. The elemental composition of the boundary lubricating film was examined by means of Auger electron spectroscopy. The results show that there are synergistic effects existing in the anti-wear and friction-reducing capabilities of REN and SN. And the complex of REN and SN possesses better lubrication abilities than that of ZDDP. It may be possible for the complex to be used as a novel and efficient and multifunctional lubrication additive in industrial application. The excellent performance of the complex attributes to the formation of a boundary lubricating film mainly composed by rare earth and tin on the rubbed surface.
