铝及铝合金的阳极化,是保护和装饰铝合金产品的主要方法。采用不同的阳极化工艺,不仅可以大大延长铝制品的使用寿命,提高产品的经济价值,并能赋于产品美丽的色彩,或者耐磨、电绝缘性能。通常使用的铝合金的阳极化,是在硫酸溶液中进行的。典型的溶液浓度为180—200克/升,阳极电流密度为0.8—1.5安/分米~2,溶液温度为13—21℃。
Anodization of aluminum and aluminum alloy is the main method to protect and decorate aluminum alloy products. Using different anodizing process, not only can greatly extend the service life of aluminum products, improve the economic value of the product, and can give the product a beautiful color, or wear-resistant, electrical insulation properties. The commonly used aluminum anodization is carried out in sulfuric acid solution. The typical solution concentration is 180-200 g / L, the anode current density is 0.8-1.5 A / dm 2, and the solution temperature is 13-21 ° C.
