In order to investigate the interaction between ionic liquid (IL) and metal deactivator,the compatibility between a protontype IL with three different metal deactivators in PAO4 was studied.The effect of IL and metal deactivators on the tribological properties of PAO4 were investigated via fourball tester.The morphology and chemical composition of worn surfaces after the tribological testing were examined using a scanning electron microscope (SEM) equipped with energydispersive X-ray spectroscopy (EDS),and the synergistic mechanism between IL and metal deactivator was discussed based on surface characterization and chemical analysis.The effect of IL on corrosion inhibition property of metal deactivators was analyzed.The results show that the antiwear and extreme pressure properties of PAO4 is significantly improved with the incorporation of IL.IL and metal deactivator exhibit slight synergistic effect in terms of antiwear and extreme pressure performance.Tribochemical film composed of FeP and FePO4 is formed under boundary condition,which plays a significant role in the wear reduction.The presence of IL will not affect the corrosion inhibition properties of metal deactivators.
