摘要

滚动轴承的磨损保护在很大程度上依赖于润滑剂。因此，在润滑剂中添加极压/抗磨损（EP/AW）添加剂，以确保轴承的低磨损运行。这些表面活性添加剂在金属表面形成摩擦学边界层（TBL），可以防止磨损。然而，商业上可用的润滑剂也含有表面活性缓蚀剂（CI），它会影响TBL的形成，从而影响EP/AW的磨损保护。为了研究CI对EP/AW磨损保护的影响，在轴向推力轴承试验台进行了试验，并对TBL进行了化学表征。结果表明，根据所使用的CI， EP/AW对磨损保护具有协同作用和拮抗作用。

Wear protection of extreme pressure/anti wear additives influenced by corrosion inhibitors in oil-lubricated rolling bearings

Wear protection in rolling bearings is heavily dependent on the lubricant. Therefore, extreme pressure/anti wear (EP/AW) additives are added to the lubricant to ensure low-wear operation of the bearing. These surface-active additives form tribological boundary layers (TBL) on the metal surfaces, which can prevent wear. However, commercially available lubricants also contain surface-active corrosion inhibitors (CI), which can influence the formation of TBL and thus the wear protection of EP/AW. To examine the influence of CI on the wear protection of EP/AW, tests on an axial thrust bearing test rig and chemical characterization of the TBL have been carried out. The results show synergistic as well as antagonistic influences on wear protection of EP/AW depending on the CI used.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
