| Outline of Final Research Achievements |
Cross-sectional TEM analyses were performed. (1) Formations of Ca ion containing oxide film on the Ti-6Al-7Nb biomaterial. Ca/P ratio can be controlled using multiple oxidations using Ca cation containing and PO4 anion containing chemical solutions. (2) Change of interface structures of interface between TiAl high-temperature material and oxidation resistance coating film. (3) A new method of suppression of hot shortness on Cu-containing steel during scale formation using Ni-shot peening.
