Anodized Aluminum: Anodization Process of Coloring Aluminum!
Late 19th century: Charles B. Dudley, a British scientist, discovered that anodizing aluminum in a strong acid improved its corrosion resistance by creating an oxide layer of uniform thickness. This is the earliest discovery of anodizing. With the continuous development and progress of science and technology, the anodic oxidation process and method have been improved and perfected, and has become a widely used surface treatment
