Abstract

Titanium oxide films were prepared using an anodic oxidation method in sulfuric acid solution on the surface ofTi6Al4Valloy at room temperature. The surface energy was obtained by the measurement of contact angles and the calculation with Owens–Wendt–Kaeble's equation.Ti6Al4Vwith anodic film after chemical treatment withNaOHaqueous solution showed excellent apatite-forming ability and produced a compact apatite layer covering all the surface of titanium after soaking in three times concentration (SBF × 3) for three days. A bioactive titania-CaP film was obtained onTi6Al4V. Scanning electron microscopy, X-ray diffraction and Fourier Transform Infra-Red were used to analyze composition changes of the bioactive film. It is concluded that the acceleration of the apatite nucleation on the anodizedTi6Al4Vwith chemical treatment in a modified simulated body fluid was attributed to the novel surface characteristics and the formation of sodium titanate hydrogel layer during chemical pretreatment. The treatment ofTi6Al4Vby anodic oxidation and subsequently inNaOHis a suitable method for providing the metal implant with bone-bonding ability.
