Abstract：Titanium and titanium alloys have been widely studied and applied as biomedical metal materials. In order
to better satisfy the requirements of low elastic modulus, biological activity after implantation in human body,
the preparation of titanium based hydroxyapatite (HA) biological composites by adding hydroxyapatite with powder
metallurgy has become a research hotspot. Based on the basic properties and existing problems of titanium and
titanium alloys, this paper summarizes the research progress of titanium based HA biological composites by powder
metallurgy such as hot pressing, powder injection molding, spark plasma sintering from the aspects of preparing
biological composites to reduce elastic modulus, improve biological activity and corrosion resistance. The representative
cases were listed separately which were preparation for titanium hydroxyapatite biocomposites by synthesis
of α type, α+β type and β type titanium alloy with HA. Moreover, the challenges faced and suggestions for
the development direction are also proposed.
