Abstract
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.
