Hydroxyapatite was prepared by sol-gel method. The phase transition regularity in heat treatment wa sstudied by DTA/TG and XRD. The effects of heat treatment process on the TLM alloy substrate's mechanical properties were also studied. The results show that temperature range should lie in 450～1000 ℃ when preparing HA coating. The HA is pure and has a higher crystallinity. The insulation heat treatment temperature should be near TLM alloy's phase transition point or lie in α+β phase. It can reduce the effects on the TLM alloy substrate and get a well bonding, and homogeneous HA coating.
