Abstract
Procedure for the coloring of anodized aluminum or its alloys, by depositing on the oxide layer produced in the anodizing of metallic pigments produced by the action of an alternating electric current in a bath containing a solution of metal salts, characterized in that the coloring it is carried out in several stages, using successively several different metal baths, with concentrations of metal salts between 1 and 500 g/l, preferably between 5 and 100 g/l, with a pH between 1 and 5, maintained at a temperature between 18 and 50ºC, preferably between 18 and 25ºC and making the pieces covered by an oxide layer with a thickness between 1 and 50 microns, in each of the baths, an electrolysis in alternating current with a current density of between 0.1 and 5 A.eff/dm2, preferably between 0.1 and 1 A.eff/dm2 and under a voltage between 5 and 80 volts and, preferably, in between 7 and 30 volts, for a duration of between 5 seconds and 5 minutes, preferably between 10 seconds and 2 minutes.
