摘要 本研究主要是以商業性純鈦做為陽極處理實驗材料,以材料的晶粒度大小差異與兩家廠商提供的材料區分為四種材料。選用六種不同的前表面處理方式與兩種不同的陽極處理電解質溶液。利用材料的晶粒度差異與兩家廠商提供的材料探討不同的材料對於陽極處理後顏色的影響;針對六種不同的表面前處理探討表面處理對於陽極處理後顏色的影響,以及不同的前表面處理是否也會影響陽極處理後顏色和色差的變化。利用硫酸及磷酸兩種電解質溶液探討陽極處理在不同濃度的酸液以及不同的種類的酸液,試片顏色及色差的變化。 最後實驗結果顯示: 試片陽極處理前的表面顏色與粗糙度會影響陽極處理 後的顏色。 當試片陽極處理前的表面性質相同時,陽極氧化膜的 厚度便成為控制顏色的主要因素。 不同的表面處理對於顏色的變化也有明顯的影響。 硫酸溶液中產生的氧化膜比磷酸溶液中所產生的氧化 膜較為厚。但是在硫酸溶液比在磷酸溶液中陽極產生 的膜表面較不均勻。 Abstract The work covered the anodizing titanium in two kinds of acid solutions at different voltages. Effects of materials and surface pre-treatment on the quality of anoding treatment were discussed. Relations between the colors and electrochemical parameters, including different kinds of electrolyte, different concentration of electrolytes, were studied in this paper. Different colors produced from various voltages depended on the thickness of the coated films. Relation between surface condition and anodizing colors were investigated. The original color and roughness of substrate were also used as reference for comparison. There are six surface pre-treatments and four kinds of materials were conducted in this study. The experimented results show that: 1. The surface conditions of base matel before anodizing and the thickness of coated film both determine the color of anodization of titanium. 2. The different surface conditions affect the color of anodizing titanium apparently. 3. The differences between two kinds of electrolyte for anodizing results are only related by the thickness of coated film and surface condition.
