| Outline of Final Research Achievements |
In the present work we examined the anodization behavior of Ti alloys containing a noble metal in fluoride containing electrolytes and the morphology of resulting oxide layers, especially focused on the formation of nanotubular oxide layers and the deposition of noble metals on their surfaces. Nanotubular oxide layers were formed on Ti-Pt alloys fabricated by an electric arc melting as well as by a magnetron sputtering, but the nanotubular structure became disordered with increasing the concentration of Pt in the alloys.Though the deposition of Pt on the surface of nanotubular oxide layers was achieved on Ti-Pt alloys fabricated by the arc melting, the deposition was not well-controlled. Furthermore, the anodization of Ta was examined in the present work as some compounds of Ta have attracted attention as functional materials. Thick nanotubular oxide layers were successfully produced, but the homogeneity of the layers was extremely low because of many cracks formed in the layers.
