マイクロ波プラズマCVD法によるチタンへのチタニアコーティング

抄録

Metal is currently widely used in dentistry, but it has an aesthetic disadvantage because of its color. In this study, TiO₂ films were prepared on titanium used as a dental metal by microwave plasma CVD for use as whiteners.The effects of microwave power (P_M) and deposition pressure (P_tot) on the adhesion strength and color of TiO₂ coating were investigated. The results suggest that a higher deposition pressure and a stronger microwave power are necessary to conceal the color of titanium and to achieve a white color, while a lower deposition pressure and a weaker microwave power are necessary to obtain good adhesion.
