摘 要：Oxide nanotubes with different diameters and lengths were fabricated on the biomedical Ti2448 alloy by anodic oxidation in neutral electrolyte.Similar to oxide nanotubes fabricated on pure titanium and its alloys,the as-grown nanotubes on Ti2448 also exhibit gradually changing chemical distribution along the direction of tube growth.Furthermore,several kinds of oxides with different valence states（MxOy）are formed simultaneously for each alloying element M,while their volume fractions vary gradually along the tube-growth direction.The findings of this study would provide insight into the effect of valence states on the desired nanotube properties and help develop ways to enhance the properties of the preferred oxide.
