The surface finish of two different processes of coloring, immersion coloring and electrolytic coloring with alternating current, of anodized AA 6061 aluminum specimens has been evaluated to determine the process that produces the best color quality of the anodic layer formed during anodization. Rectangular specimens 0.5 cm thick, 5 cm long and 2.5 cm wide were used, with a total exposed area of 0.325 dm2. For the anodization process, a solution of sulfuric acid with a concentration of 20% was used, at an amperage of 1.5 A / dm2 and a time of 30 minutes. For immersion coloring a solution of an organic dye, cochineal carmine at a concentration of 15 g / L, at a temperature of 90 to 95 ° C for a time of 10 minutes was used. For the electrolytic coloring a solution of Nickel Sulfate heptahydrate was used: 300 g / L, Nickel Chloride hexahydrate: 60 g / L and Boric Acid: 30 g / L; at an alte...
