Outline of Final Research Achievements

In this study, high-performance titanium was examined in order to expand the industrial use of titanium and titanium alloys. It was examined whether anodic oxidation or thermal oxidation of hard coatings such as TiC and TiN films deposited on titanium substrates can produce high-performance coatings. As a result, by changing the thermal oxidation temperature and the elemental content of the hard film, it was possible to create high-performance films with superior wear resistance and photocatalytic properties to those of titanium.

Academic Significance and Societal Importance of the Research Achievements

本研究は,優れた特性を有し工業的に広く用いられるチタン(Ti)およびその合金の欠点である耐摩擦摩耗性改善し,さらに光触媒性を具備した高機能化なTiを作成できた.すなわち,PVD法などで成膜される硬質のTiCやTiNコーティングを熱酸化処理することで,TiO2が有する光触媒性の機能を併せ持つ高機能な皮膜を創製することができた.この結果からTiのさらなる利用拡大が期待できるため本研究の社会的意義は大きいと思われる。また,熱酸化温度による耐摩耗性と光触媒効果の影響を定量的に評価し,構造解析も行い実証的に検討した点で学術的意義も大きいと思われる.
