Abstract

Procedure for the electrolytic dyeing of aluminum or aluminum alloy objects, previously oxidized by the anodic route, in which an alternating current flows between the object to be dyed and a counter electrode, preferably molybdenum, tungsten or titanium, in an aqueous solution acid of a metal salt, characterized in that a water-soluble compound of a metal of subgroup VI (VIb) of the periodic system is used in the acidic aqueous solution, preferably molybdenum or tungsten, in which the valence of the metal is different from its main valence.
