Titanium and titanium alloys have widely been used in biomedical applications as main substitutes for hard human tissues. To better meet the needs of safety, comfort, and durability of titanium and titanium alloys after implantation in the human body, the surface modification treatment of titanium and titanium alloys has become a research hotspot. In this review, based on the basic properties and existing problems of titanium and titanium alloys, the methods of surface modification for titanium and titanium alloys are introduced to improve their mechanical properties, biocompatibility, and bacteriostatic/antibacterial properties. Furthermore, the current challenges and prospects have been presented in this paper.
