摘　　要：采用水热电化学沉积法制备HA/TiO2复合涂层,研究电解液中TiO2加入量和沉积温度对HA/TiO2复合涂层物相组成及表面形貌的影响,同时对复合涂层的结合强度、生物活性进行了研究。结果表明,HA/TiO2复合涂层由HA和TiO2组成,其中HA晶体含量随电解液中TiO2加入量的增加而减小;HA晶体尺寸随电沉积温度升高呈增大趋势;在120℃,15 g/L TiO2条件下,电沉积HA/TiO2复合涂层的结合强度达到18 MPa。TiO2的加入没有影响涂层的生物活性。HA/TiO2 composite coating was deposited by hydrothermal electrochemical deposition method .Effects of the adding amount of TiO2 in the electrolyte and deposition temperature on the surface morphology and phase composition of HA /TiO2 composite coating were studied, at the same time, bonding strength and biological activity of the composite coating were investigated .The results show that HA/TiO2 composite coating is composed of HA and TiO 2 .With the amount of TiO 2 increasing , the content of HA decreases , with electro deposition temperature increasing , the size of HA increases .The bonding strength of HA/TiO2 composite coating reaches to 18 MPa under the condition of 120 ℃and 15 g/L TiO2 .The addition of TiO 2 do not affect the biological activity of coating .
