| Research Abstract |
The purpose of this study is formation of excellent surface oxide films to improve the biocompatibility on a Ti-6Al-7Nb (α+β) 2 phase-type alloy by means of anodic oxidation, involving Ca cation and hydrothermal process. Nano-tube surface film was generated even there was some difference in tube diameter between α and β phases. And Ca was incorporated into the nano-tube structure. Micro-arc oxidation process in the chemical solution containing Ca ion made the surface film containing Ca cation. We find that ingredients of the chemical solutions affected phases in the oxide film and the structure of the interface and defects.
