文摘

Two kinds of oil-soluble ionic liquids (ILs) with the same cation but different anions are synthesized, which exhibit more favourable solubility property in PAO10 than tradition ILs. The tribological results indicate that the mixtures perform excellent lubricating performance compared with neat PAO10 for steel/steel contacts. Many characterization methods, such as quartz crystal monitor (QCM), plasma treatment, external potential and X-ray photoelectron spectroscopy (XPS), are applied comprehensively to clarify the lubricating mechanism of ILs as additives.
