铝及其合金由于有比重轻、易加工等特点,在工业上应用越来越广泛,为了提高铝及其合金的抗蚀性能和装饰性,一般采用阳极氧化工艺使铝表面生成一层氧化膜。但长期以来以染单色为主,近来随着人民生活水平不断提高,对铝表面装饰也有新的要求——彩色化。广大表面处理工作者为了适应人民群众新花色要求已试验成功新的彩色氧化工艺,从而使氧化膜外观色彩绚丽,美观 Aluminum and its alloys are widely used in industry due to their light weight and easy processing. In order to improve the corrosion resistance and decorative properties of aluminum and its alloys, anodic oxidation is generally used to form an oxide film on the surface of the aluminum . However, monochrome has long been the dominant color. Recently, as people’s living standards continue to improve, there are also new requirements for aluminum surface decoration - colorization. The majority of surface treatment workers in order to adapt to the new flower color requirements of the people have been tested successfully new color oxidation process, so that the appearance of colorful oxide film beautiful, beautiful
