本文主要介绍了利用光干涉效应原理的工艺着色阳极氧化铝,并对干涉色涂层的微观结构进行了初步分析。将经过常规硫酸阳极氧化后的铝试样,在磷酸溶液中作短时间的阳极氧化扩孔处理,再置于普通电解着色液中进行电解着色,即可获得性能优异的干涉色涂层。阳极氧化铝中的干涉着色效应,来源于沉积金属层表面和阳极膜/铝基体界面的两束散射光的相互作用。 This paper mainly introduces the process of anodizing aluminum by the principle of optical interference effect, and makes a preliminary analysis of the microstructure of the interference color coating. After conventional anodic oxidation of sulfuric acid sample of aluminum in phosphoric acid solution for a short time anodizing reaming treatment, and then placed in the general electrolytic coloring solution for electrolytic coloring, you can get high performance interference color coating. The interference coloring effect in anodized aluminum originates from the interaction of the two scattered lights at the interface of the deposited metal layer and the anode film / aluminum substrate.
