摘要
采用周期换向电流法对含铜较高的铝合金进行电解氧化发色。分别对温度与氧化电流密度等影响氧化膜生长速度与质量的工艺条件做了分析研究 ,取得了实用的工艺操作规程。研究结果表明 :应用周期换向电流法可以在硫酸溶液中对较难氧化着色的铝铜合金进行氧化发色 ,得到黄 -黄绿 -绿 -黑绿 -黑系列颜色的氧化膜。
Periodic rreverse direct current was employed in the electrolytic anodizing and coloring of a type of aluminium alloy with high copper content. Effects of technological conditions such as temperature and current density on the growth rate and quality of the anodizing film are analysed, and a practical operating technology is obtained. The experimental results show that AlCu alloy, which is difficult to be treated usually, can be anodized and colored in sulfuric acid with periodic reverse direct current, and anodizing film with a series color, such as yellow, yellowgreen, green, blackgreen and black color can be obtained.
