[Deposition of hydroxyapatite on the titanium oxide nanotube in simulated body fluid].
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.
