Abstract

The present work demonstrates the self-organized nanotube oxide layers on Ti-50Ta alloy by anodic oxidation. Highly ordered nanotube layers can be formed on the alloy under different anodization parameters. In aqueous solution containing glycerol and NH4F, the diameter of the nanotubes can be strongly influenced by the applied potential, while length of the nanotubes is determined by the electrolyte temperature and anodization time. Nanotubes with hexagonal arrangement are formed under appropriate condition. Each nanotube exhibits hexagonal prism shape and is surrounded by six others. The amorphous oxide phase of the nanotubes transforms to anatase and rutile phases after heat treatment..
