離子鍍含銅陶瓷抗菌裝飾鍍膜的發色技術

Ion Plated Copper-containing Ceramic Coatings for Antimicrobial and Decorative Purposes

近年來裝飾性陶瓷鍍膜已在衛浴五金、首飾、手機等領域廣泛應用，因此裝飾性陶瓷鍍膜術在市場不斷的競爭及需求下更需創造出獨特的產品特色。為求鍍膜外觀顏色之多樣化及兼具抗菌效能，本研究擬結合電弧離子鍍（發射金屬鈦）及磁控濺鍍法（發射銅金屬）於同一腔體，於預電鍍鎳／鉻之銅基材表面被覆兼具發色及抗菌之含銅鈦系陶瓷鍍層，進一步對其保固性做探討。研究結果顯示，含銅鈦系陶瓷鍍膜之表面視硬度、耐磨性和耐蝕性皆高於預電鍍鎳／鉻之黃銅基材。隨著施鍍過程中氧氣通入時間由10秒增加至60秒，鍍膜外觀顏色依序呈現金黃色、紅色、藍色、紫色的變化趨勢；在氧氣和乙炔同時導入後亦呈現相同之變化趨勢，唯CIE色度座標之L*（明暗軸）值將明顯的下降。

Widespread applications of decorative ceramic coatings have been seen in sanitary wares, jewelry, and cellular phones and been tremendously studied in recent years. The development of these products is also evolving. An arc ion plating (AIP) technique (for titanium emission) in combination with magnetron sputtering method (for copper emission) was utilized in one single chamber in order to synthesize copper-containing TiCxNyOz antimicrobial coatings for decorative and protection purposes in this study. Experimental results showed that the copper-containing TiCxNyOz coating greatly enhanced the apparent surface hardness, wear resistance, and corrosion resistance of the Cu-35Zn material, in comparison with a pre-electroplated Cu-35Zn material. The appearance of the coatings noticeably varied in color from golden yellow, red, blue to eventually purple as the deposition time (10 ~ 60 s) increased under a constant oxygen flow. Moreover, under simultaneous constant flows of acetylene and oxygen, the appearance of the coatings varied in color in the same way, except that L* of CIE chromaticity decreased to a lower level.
