Abstract

Integral coloring of aluminum and its alloy with the elecrolytic solution of sulfosallicylic acid and sodium hydroxide was investigated in this study. Addition of hydrogen peroxide and potassium permanganate accelerated the anodizing speed and deepened the color of anodized film. Electron microscopic study was also performed on the surface and cross section.
