The invention discloses a variable-angle, different-color and multi-colored anodizing method. The method comprises adjusting the membrane holes of an anodized film on the surface of a component to be treated from an upper and lower diameter structure to a variable diameter structure; and arranging electrolytic coloring in the membrane holes. In the deposition layer, the portion of the film hole located above the upper surface of the electrolytically colored deposition layer includes at least two hole segments with different inner diameters. The method can effectively control the processing process, interfere with the color performance of the final product, and can realize the variable color effect of vertical and small-angle light color, parallel and large-angle observation as dark color, and the multi-colored product can meet the existing subdivision. Special visual needs of the high-end market. At the same time, it can also pass through a good sealing process in the subsequent process, and its performance indicators can meet the important corrosion resistance test and weather resistance test. The products obtained by the method provided in this application can achieve the same corrosion resistance and weather resistance as ordinary oxidation or electrolytic coloring. . |
