Abstract
1.process for the electrolytic coloration of anodized aluminum, characterized in that in a first phase thereof an aluminum oxide layer is produced on the metal, for which a sulfuric acid bath with a concentration of 150 to 200 gr/is used. L, a voltage between electrodes of 12 to 20 volts and a current density of 1 to 2 a/dm2, the duration of this treatment being between 15 and 60 minutes, while the second phase of the process consists of the introduction of the metal in a dyeing bath in which two different electrolytic stages are established, of which, in the first one, the metal is subjected to a continuous pulsating voltage, while in the second one a negative pulsating direct voltage is programmed on the form wave of the first stage.
