| Abstract Scope |
Titanium is the material of choice in a plethora of applications due to its favorable specific strength and excellent corrosion resistance. Titanium is also increasingly popular for biomedical devices such as implants owing to its excellent biocompatibility. However, a significant shortcoming of titanium alloys is their poor tribological surface properties, including poor wear resistance.
This contribution addresses thermochemical surface engineering and heat treatment of titanium alloys. The state-of-the-art and historical perspectives of surface hardening of titanium alloys are presented. New advances in low, medium, and high-temperature thermochemical surface engineering of titanium alloys are reported. The importance of the thermal impact from surface treatment (heat treatment) on the core microstructure is emphasized. Lastly, the optimization of microstructure by heat treating titanium alloys is addressed, with a particular focus on the role of post-heat treatment of laser powder bed fusion additively manufactured titanium alloys. |
