Abstract

Anodic oxidation was conducted to Ti-Nb-Sn biometallic alloy for the purpose of giving photo-induced properties without losing the low Young's modulus of the alloy. The anodic oxide consists of primary TiO₂ with small amounts of Nb₂O₅ and SnO. Rutile-structured TiO ₂ prepared in an electrolyte solution containing 1.2 M sulfuric acid exhibits photocatalytic activity and superhydrophilicity under ultraviolet (UV) light illumination, and superhydrophilicity in the absence of UV light illumination. The Young's modulus of Ti-Nb-Sn alloy with anodic oxide demonstrates a low value of approximately 50 GPa, which expands its application of the alloy as biomedical materials by adding photocatalytic sterilization function.
