Abstract:	本研究採交流電陽極處理，於鹼性鍍液中使鍍鋅鋼鐵基材表面生成均勻被覆層，增加鋅表面抗蝕性，並產生鮮明色彩，顯著提升其經濟價値。研究中利用交流電於不同極板上，同時處理相同試片，產率及抛力皆大幅提升。並藉由電鍍液中添加適當金屬鹽來獲得色彩均勻的綠色、藍色、灰色、白色、棕色、暗紅色等六種硬質被覆層。同時建立一系列處理步驟，大幅增加抗蝕性，並減少腐蝕產物生成，改善鍍鋅鋼件外觀。實驗應用於螺栓、扣環等鍍鋅鋼配件著色效果良好，且提供有機塗料優良附著表面，研究中並做各種相關特性的測試，探討被覆層表面結構及電化學性質。 The anodic coatings of galvanized steel are of present interest because of their improved corrosion resistance against the atmospheric corrosion. Investigation were carried out to find suitable conditions for producing anodic coatings of controlled quality on the galvanized steel. The present work was able to obtain coatings of six different colours. Anodized zinc performs significantly better corrosion resistance than the bare galvanized steel as evaluated by the salt fog test.
