High density, well ordered and uniform titanium oxide nanotube arrays were fabricated on the surface of titanium substrate by anodic oxidation in 0.5 mol/L H3P04 + 0. 138 mol/L NaF solution. Then hydroxyapatite coatings were deposited in a simulated body fluid (SBF). The morphology of titanium oxide nanotubes and the coatings was observed by means of scanning electron microscope (SEM). The phase composition of the coatings was determined by X-ray diffractometer (XRD). The phenomenon of polarization was studied by the CHI660A Electrochemical Workstation. The titanium oxide nanotube was found to be about 100 nm in diameter. The result of the samples soaked in SBF showed that the hydroxyapatite coatings were precipitated on the nanotube of titanium oxide.
通过在0.5 mol/L H3P04 + 0. 138 mol/L NaF溶液中进行阳极氧化，在钛基底表面制备了高密度、排列有序且均匀的二氧化钛纳米管阵列。然后在模拟体液（SBF）中沉积羟基磷灰石涂层。通过扫描电子显微镜（SEM）观察二氧化钛纳米管和涂层的形貌。用X射线衍射仪（XRD）测定涂层的相组成。利用CHI660A电化学工作站研究极化现象。发现二氧化钛纳米管的直径约为100 nm。浸泡在SBF中的样品结果表明，羟基磷灰石涂层沉淀在二氧化钛纳米管上。
