Effects of electrochemical deposition time on the phase, morphology, bioactivity of hydroxyapatite (HA) coating and the bonding strength with the substrate were investigated adopting alkali-treatment of titanium alloy followed by electrochemical deposition. Results show that the electrochemically deposited coatings prepared on the surface of alkali-treated titanium alloy are composed of flake HA phases, and the electrochemical deposition time has no effect on the phase composition of the coatings, but will bring impact to the coating thickness. After 60 min deposition, the obtained HA coatings is very compacted and has the bonding strength with the substrate up to 17.85 MPa. It is shown that the HA coatings obtained after each deposition time have good bioactivity. In the simulated body fluids (SBF), CO32- substitutes PO43- in the HA into apatite to form steamed bun-shaped carbonated hydroxyapatite（CHA），with the diameter of 7-8 μm. After being immersed in SBF for 3 days，the CHA can be spread all over the surface of HA.
