| Abstract: | 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.
