CP Grade II titanium was first anodized in order to form TiO2 nanotubes, and then the TiO2 nanotubes were coated with hydroxyapatite using the sol-gel method. The electrochemical properties of pure Ti, anodized TiO2 nanotubes, and HA-coated TiO2 nanotubes were investigated using potentiodynamic polarization and impedance tests. The sol-gel-coated HA nanoparticles were observed to sufficiently penetrate into the TiO2 nanotubes, and the polarization resistance of the HA-coated titanium nanotubes was higher than that of those that had just been anodized. In conclusion, the HA coating on the TiO2 nanotubes provides improved electrochemical properties and can be effective in overcoming the negative influence of passive TiO2 films.
