• 中文摘要： 本文依下列兩部份進行研究: (a)鋁材先於20wt%硫酸溶液中以方波形成多孔陽極膜, 再於以硫酸銅為主之溶液中以交流著色。(b)鋁材先於20wt%硫酸溶液中以直流形成多孔陽極膜, 再於以硫酸銅為主之溶液中以方波著色。陽極膜厚隨著陽極氧化之時間增加而增加, 而其成長速率卻隨陽極氧化時間增加而減少。陽極膜硬度則隨著陽極氧化之時間先增加而後減少。陽極膜硬度可於膜成長中在一特定時間達到一極大值。此外, 陽極膜硬度與厚度並無必要之相關性。鋁材以方波陽極氧化之膜可著上燦爛具光澤的顏色, 而且以不同角度觀察時, 會因光之干涉而呈現其他的顏色。以高電壓及高頻率之方波電解著色可得較深的顏色(如褐色), 而使用低電壓及低頻率, 則色較淡(如灰色)。色調較光澤易受氣候之影響。
• 英文摘要： The study is divided into two parts as follows: (a) Porous anodic film on aluminum is formed by square-wave current in 20% sulfuric acid aqueous solution and then colored by alternation current in a solution featuring cupric sulfate, and (b) Porous anodic film on aluminum is formed by direct current in 20% sulfuric acid and then colored by square-wave current in a solution featuring cupric sulfate. The thickness of the anodic film increases with increasing anodizing time; however, the growth rate of the anodic film decreases with time. The microhardness of the anodic film increases at first and then starts to decrease with anodizing time. It shows that the microhardness of the anodic film during growth can reach a maximum value at specific time. Besides, the film microhardness is not necessarily dependent of the thickness of the anodic film. It is observed that the films on aluminum anodized by square-wave current can be colored with rich and lustrous colors and the films, when they are seen obliquely, appear another color due to optical interference. The colors of the films colored at higher voltages and frequencies by square-wave current are darker (such as brown), while the colors of the films colored at lower voltages and frequencies are lighter (such as gray). The hue differences are more influenced than the lightness differences by weathering.
