Formation and Characterization of Hydroxyapatite Coating Prepared by Pulsed Electrochemical Deposition

Keywords： AZ91D magnesium alloy , pulsed electrochemical deposition , hydroxyapatite , bioactivity coating

采用交流脉冲沉积法在AZ91D镁合金表面合成了羟基磷灰石涂层.考察了交流脉冲电压、沉积时间及电解液添加剂等电化学沉积参数对羟基磷灰石涂层的形貌、微观结构、元素组成及电化学性能的影响.结果表明,当脉冲电压为11oV时,纳米级别的羟基磷灰石涂层表面更为均匀,孔隙度更小,且其XRD的特征衍射峰更为突出.当电解液中添加了NaNO3和H2O2后,羟基磷灰石颗粒和涂层表面形貌均得到优化;同时,极化曲线和交流阻抗测试结果表明该涂层在模拟体液中的耐蚀性能提高.浸泡实验结果表明,该涂层有利于诱导羟基磷灰石的形成,从而提高涂层的生物活性.
