“…In Fig. 3(b)-(c), the peaks at 518 cm À1 and 639 cm À1 slightly shift toward to small wavenumber, which is correlated to the change of crystalline size of TiO 2 [19]. The increasing intensity of the anatase peak at 639 cm À1 results from the formation of NbÀ ÀO bond [20].…”

“…Meanwhile, in the case of Ti-25Nb alloy, a low water contact angle was observed even on TiO 2 layers with lower f A values such as 0.2 and 0.4. The effect of Nb doping on the photocatalytic activity of TiO 2 was reported to be complex [47]. Further studies on the chemical state, concentration, and distribution of Nb in the TiO 2 layer are required.…”

Two-step thermal oxidation was proposed for Ti and Ti alloys as a surface-treatment process for preparing an anatase-containing TiO 2 layer. This process consisted of treatment in a CO-containing atmosphere (first step) and subsequent treatment in air (second step). In this chapter, first, the current status of TiO 2 coating onto Ti and Ti alloys for biomedical applications is reviewed; then our recent work on the phase and microstructure of TiO 2 layers prepared on commercially pure (CP) Ti, Ti-25mass%Mo alloy, and Ti-25mass%Nb alloy by two-step thermal oxidation is described. The anatase fraction in the TiO 2 layer was controlled through process parameters such as the second-step temperature. Finally, photocatalytic activity of TiO 2 layers formed on the Ti and Ti alloys is evaluated, including: results of water contact angle, decomposition of methylene blue, and antibacterial effects.
