由我校化工系暨调和副教授承担的“铝和铝合金阳极氧化膜的电解着色”课题,经两年多的研究取得成果,于1988年12月通过部级鉴定.本成果的基本原理:铝及铝合金在硫酸中进行阳极氧化后,形成由阻挡层和多孔层组成的氧化膜,将氧化后的铝制件浸入含有金属盐或金属含氧酸盐的电解液中,施加8—12V交流电,由于氧化膜的阻挡层具有整流作用,当采用比铝电位正的导体作对极
By the Department of Chemical Engineering and co-ordination associate professor of “aluminum and aluminum alloy anodizing film electrolysis coloring,” the subject of more than two years of research results, in December 1988 through ministerial level identification of the basic principles of the results : Anodizing the aluminum and the aluminum alloy in sulfuric acid to form an oxide film composed of a barrier layer and a porous layer, immersing the oxidized aluminum piece in an electrolyte containing a metal salt or a metal oxoacid salt, applying 8- 12V AC, due to the oxidation of the barrier layer has a rectification effect, when the use of positive than aluminum potential conductor as the counter
