Preparation and Properties of Cerium-containing Hydroxyapatite Coating on Commercially Pure Titanium by Micro-arc Oxidation

采用微弧氧化法在含有乙酸钙、β-甘油磷酸钠、硝酸铈的电解液中在纯钛金属表面原位生成了多孔含Ce羟基磷灰石生物涂层.用XRD、SEM、EDS、细胞培养等方法对膜层的厚度、物相、成分组成及生物相容性进行了研究.结果表明膜层粗糙多孔,厚度为15～25μm,与钛基体之间无明显界面;膜层表面主要物相为含Ce的羟基磷灰石;细胞培养结果表明膜层具有良好的生物相容性.
