摘    要:以硝酸钙和五氧化二磷为前躯体,使用溶胶-凝胶法制备出羟基磷灰石,并使用浸渍提拉法在纯钛表面合成羟基磷灰石涂层.使用XRD对涂层中的相结构进行分析,以确定不同加热温度以及不同涂层层数对羟基磷灰石涂层性能的影响.结果表明:随加热温度升高,羟基磷灰石的结晶度和体积分数先升后降.在800℃下,羟基磷灰石的结晶度最高,体积分数也...

关 键 词:溶胶-凝胶法  羟基磷灰石    生物材料

Abstract:The calcium nitrate and phosphorus pentoxide were used as precursor to prepare hydroxyapatite layer by sol-gel method,followed by a dipping-coating method to coat hydroxyapatite layer onto Ti.Phase formation was investigated by XRD to study the influence of temperature and thickness of layer on the property of hydroxyapatite layer.According to the experimental results,with lifting of the heating temperature,crystallinity and volum fraction of hydroxyapatite in the layer first increase and then drop.The crys...
