本文介绍日本有关铝或铝合金多色电解着色法及铝合金多彩色被膜制造方法的部分新技本.关于铝合金着色,以往广泛采用二步电解法.针对二步电解法存在的问题.发展成为三步电解法、一步电解法,甚至一个工序同时形成两种以上的多彩色着色法.下面从工厂实用性出发作一简要介绍. In this paper, some new techniques about the multi-color electrolytic aluminum or aluminum alloy coloring method and the multi-color aluminum alloy multi-color film manufacturing method are introduced in this paper.For the aluminum alloy coloring, the two-step electrolysis has been widely used in the past. A three-step electrolysis, one-step electrolysis, or even a process of forming more than two kinds of multi-color coloring method. The following from the factory for a brief introduction of practicality.
