The influence of nanophases (titanium hydride compounds) on the formation of nanostructural titanium oxide by electrochemical treatment was investigated by electron spectroscopy for chemical analysis, thin film X-ray diffractometer, transmission electron microscopy, and scanning electron microscopy. Nanostructured TiO2 was formed after anodization following cathodic pretreatments, which formed a nano-TiH2 layer. The nano-TiH2 is directly dissolved due to anodization, which in turn, is changed to nanoporous TiO2. The nano-TiH2 plays an important role in forming the nanoporous TiO2. The association of anodization with cathodic pretreatment not only produces the nano-TiH2 layer, but also results in formation of the nanostructured TiO2. It is believed that bioactive titanium implants with this nanostructure after oxidation treatment can enhance the integration of bone interface contacts.
