采用微弧氧化技术在纯钛表面制备了花瓣状磷灰石/二氧化钛（TiO 2）涂层。对磷灰石/TiO 2复合涂层的表面形貌、晶体结构、化学组成和结合状态进行了表征。涂层由双层（磷灰石层和TiO 2层）结构组成。内部TiO 2层和外部磷灰石层的平均厚度分别约为6 μ m和16 μ m。外部磷灰石层是多孔的，并呈现花瓣状图案。磷灰石层由羟基磷灰石（HA）和碳酸磷灰石组成，内部TiO 2层由锐钛型和金红石组成。(c)2010 Elsevier B. V.保留所有权利。
Petal-like apatite/titania (TiO2) coating was prepared on commercially pure titanium (Ti) by micro-arc oxidation in electrolyte containing calcium and phosphate for the first time. The surface morphology, crystalline structure, chemical composition and binding state of the apatite/TiO2 composite coating were characterized. The coating consists of a double-layer (apatite layer and TiO2 layer) structure. The average thickness of the inner TiO2 layer and the outer apatite layer is about 6 gm and 16 mu m respectively. The outer apatite layer is porous and exhibits petal-like pattern. The apatite layer consists of hydroxyapatite (HA) and carbonate-apatite and the inner TiO2 layer consists of anatase and rutile.
