摘要
通过在钢圆盘表面形成聚四氟乙烯（PTFE）薄膜，并使用水基离子液体作为润滑剂，系统地研究了聚四氟乙烯薄膜和水基离子液体的固液协同效应。结果表明，聚四氟乙烯薄膜具有优异的摩擦学性能，并在滑动电接触界面的电气条件下保持良好的绝缘能力。当使用水基乳酸离子液体作为润滑剂时，聚四氟乙烯薄膜在 2 N 负荷下的 COF 值小于 0.01，实现了超低摩擦。润滑机理分析表明，聚四氟乙烯薄膜和钢摩擦副表面形成了两种保护膜。这些保护膜有效阻止了摩擦副之间的直接接触，显著提高了摩擦学性能。
Study on ultra-low friction performance of PTFE film combined with water-based ionic liquid lubrication at electrical contact interfaces
By polytetrafluoroethylene (PTFE) films on the surface of steel disc and using water-based ionic liquids as lubricants, the solid-liquid synergistic effect of PTFE films and water-based ionic liquids was systematically investigated. The results showed that PTFE films exhibited excellent tribological performance and maintained good insulation capabilities under electrical conditions in the sliding electrical contact interface. When using water-based lactate Ionic liquids as lubricants, the PTFE film achieved a COF of less than 0.01 under a load of 2 N, realizing ultra-low friction. The analysis of the lubrication mechanism revealed that two types of protective films were formed on the PTFE film and steel friction pair surfaces. These protective films effectively prevented direct contact between the friction pairs, significantly enhancing tribological performance.
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.
