摘要
Several imidazole phosphate ionic liquids with varying carbon chain length have been synthesized at room temperature. Corrosion characteristics and tribological properties of these synthesized ionic liquids were studied using four-ball friction and wear testing machine. Its lubrication mechanism was also investigated by means of electron microscopy and X-ray photoelectron spectroscopy. The experimental results showed that no corrosion was generated when the imidazole phosphate ionic liquid was applied to steel-steel pair. Meanwhile, the imidazole phosphate showed excellent anti-wear and lubricating performances, its frictional performance was related to the polarity of ionic liquids. It is suggested that the ionic liquids react with friction surface to form a protective film of iron phosphate and result in reduction in friction and wear.
