电解法制取彩色铝膜的新工艺

Colourful Electrolysis of Aluminium

在硫酸中进行阳极氧化的基础上，通过正交试验获得了采用磷酸进行二步阳极化处理后在硫酸镍溶液中电解着色并在磺基水杨酸中进行电解处理以制取鲜艳、多色彩膜系列的工艺条件。同时还对彩色膜的性能进行了测定和评估。利用Ｘ－衍射仪和ＳＥＭ仪对膜成分又结构进行了测定，并对有关机理进行了分析。

The technological conditions through rhombic tests were put forward in theresearch.On the basis of anodizing in sulphuric acid, phosphoric acid is used twice for anodictreatment. And then electrolytic colouring with Nickel Sulphate is completed.Finally,brighter andmore colourful films are produced by sulphosalicylic acid electrolysis. The property of colouful filmswas measured and evaluated. Morever.the composition and structure of the films was determined with x-ray-diffraction and SEM.The mechanism of colouring has been discussed in this paper.
