摘　　要：在含有0.04mol/Lβ-甘油磷酸钠(β-GP)和0.10mol/L醋酸钙(CA)电解液中对Ti进行微弧氧化。结果发现:微弧氧化方法适合于Ti在甘油磷酸钠和醋酸钙电解液中形成富含有Ca和P的氧化膜。氧化膜粗糙多孔,电流密度和最后电压分别为200A/m2和430 V形成的氧化膜主要由锐钛矿型Ti O2,金红石型Ti O2和非晶相组成。低温下进行水热处理,羟基磷灰石晶体在氧化膜的表面沉积。用扫描电镜、能谱仪、X射线衍射、X射线光电子能谱对氧化膜进行了研究。Microarc oxidation （MAO） was performed on Ti in the electrolyte containing 0.04mol/L β-GP and 0. 10mol/L CA. It was found that the MAO method is suitable for Ti to form oxide film containing Ca and P in the electrolyte of β-GP and CA. The oxide films were rough and porous. The oxide film formed at 200A/m^2 and 430V final voltage mainly consists of anatase, rutile and amorphous phase. Hydroxyapatite crystals were precipitated on film surfaces at low temperature hydrothermal treatment. The oxide films were investigated by means of scanning electron microcopy （SEM）, energy dispersion X-ray microanalyser （EDX）, X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）.
