XPS Characterization of TiO Nanotubes Growth on the Surface of the Ti15Zr15Mo Alloy for Biomedical Applications.

Ti15Zr15Mo (TMZ alloy) has been studied in recent years for biomedical applications, mainly due to phase beta formation. From the surface modification, it is possible to associate the volume and surface properties with a better biomedical response. This study aimed to evaluate the possibility of using anodization to obtain TiO nanotubes due to the presence of valve-type metal (Zr) in their composition.

Modification of the Ti15Mo alloy surface through TiO nanotube growth-an in vitro study.

In this study, ordered and uniform TiO nanotubular structures were obtained on the surface of the Ti15Mo alloy by anodic oxidation. The amorphous state of TiO nanotubes formed under different anodization conditions was investigated. Crystallization of TiO into anatase phase occurs during annealing at temperatures of around 400°C, whereas anatase to rutile transformation starts around 500°C and is completed at 800°C.
