根据含氟羟基磷灰石(FHA)陶电沉积瓷技术,将纳米二氧化钛微粒加入电解液中,在钛基体表面进行电化学复合共沉积,获得了含氟羟基磷灰石复合纳米TiO2涂层(FHA/n-TiO2).对FHA/n-TiO2纳米复合涂层进行了真空烧结处理,并通过X射线衍射(XRD)、扫描电镜(SEM)、红外光谱(IR)、X射线光电子能谱(XPS)等技术对其进行了表征,比较了HA、FHA和FHA/n-TiO2涂层在柠檬酸改性的磷酸缓冲溶液中的抗溶解性能和结合强度.结果表明,真空烧结处理可使复合涂层中晶体的择优取向发生改变,晶体形态由针状转变为颗粒状；在FHA涂层中复合纳米TiO2微粒可以显著提高涂层与钛基体的结合强度而不影响其抗溶解性.
