摘要
采用阳极氧化-电化学沉积-水热合成法制备Ti／TiO2／Ca10（PO4）6（OH）2生物陶瓷复合涂层。利用D／Max-rB型X射线衍射仪（XRD）分析涂层的组织结构，用Sirion200型扫描电镜（SEM）观察涂层的表面形貌。结果表明：钛合金（Ti-6Al—4V）板经以10％的硫酸为电解液和电压为120V条件下的阳极氧化，形成孔径大约为100-200nm的多孔氧化膜，再经电化学沉积，得到尺寸大小约200～400nm的针状CaHPO4，最后经盛有浓度为0．1mol／L的NaOH水溶液、温度为200℃的高压釜中水热合成10h，针状的CaHPO4转变为片状的Ca10（PO4）6（OH）2。
Ti/TiO2/HA composite coatings were prepared with the anodic oxidation-electrochemistry - hydrothermal method . The morphologies and the crystallization of the films were investigated by means of X-ray diffractometer （XRD） and scanning electron microscope（SEM）. The results show that the TiO2 porous films can be obtained by anode oxidation using 10% H2SO4, voltage of 120V on the surface of Ti-6Al-4V alloy , and the aperture size is about 100-200nm. The acerate CaHPO4 with size of 200-400nm can be gained by the electrochemical deposition, Ultimately, the acerate CaHPO4 is changed into the sheet Calo （PO4）6 （OH）2 after being treated with 0. 1mol/L NaOH in autoclave at 200℃ for 10 hours.
