Inspired by non-smooth surfaces in nature, surface texture which can play positive roles in tribology such as capturing debris, storing lubricant and reducing the contact area during service has been regarded as an effective approach to improve the tribological behaviors of materials. Some beneficial results in enhancing tribological properties of titanium alloys have been obtained. This review was focused on the studies of design and processing of surface texture, mechanisms of friction reduction and wear-resistance, duplex treatments with surface technology applied on titanium alloys. Research progress on surface texture for improving tribological properties of titanium alloys was summarized. The prospect of surface texture related research ideas and methods of titanium alloys were suggested.
