LD31铝合金黑色化学氧化膜新技术在游泳馆门窗中的应用

Application of new technology of black chemical coversion coating for Aluminum alloy LD31

游泳馆门窗铝合金表面着膜黑色,既可提高铝件的吸热与防蚀性能,又可提高其视觉装饰效果.本文采用一种通过两步化学氧化着黑色的新技术,得到了结合力好、耐蚀性强、颜色鲜艳美观的铝合金黑色氧化膜.

The surface of natatorium＇s windows and doors dying black,may not only enhance the aluminum heat absorption and the performance for preventing from corrosion,it can also enhance its visual decoration effect. This article has proved that it can obtain black chemical coversion coating for aluminum alloy 6063,of which the binding force is better, the corrosion resistance is stronger and the color is more bright through the new technology of twostep black chemical coversion coating.
