Abstract: Titanium alloys have been widely used in engineering fields due to their high corrosion resistance, good
toughness and specific strength and many other excellent properties. However, titanium alloys are especially sensitive to
adhesive wear with poor wear resistance under higher loads. In past several decades, many researchers have found that
the textured surface can improve tribological performance, which is suitable for severe working environments. The
influence of surface texture on the tribological properties mainly depends on various factors such as texture shape, depth
and size parameters and processing accuracy. In past twenty years, ionic liquids have been extensively and intensively
