Abstract

Engineering polymers with high glass transition temperature have been widely used in dynamic friction systems by oil or solid lubrication. However, in high-load systems, oil lubrication is less efficient due to the viscosity decrease at higher temperatures induced by friction heat. [Bmim][PF₆] ionic liquid was used and compared with traditional L-HM46 oil and solid PTFE. Taking advantage of high [Bmim][PF₆] viscosity, strong steel-[Bmim][PF₆] but poor PEEK-[Bmim][PF₆] interaction, the [Bmim][PF₆] lubricated PEEK/steel slide falls in hydrodynamic lubrication and elastohydrodynamic lubrication region under 150-1500 N. While the oil and PTFE both failed to lubricate under 800 N.
