Abstract

Procedimiento para la producción de recubrimientos protectores coloreados sobre artículos de aluminio o aleaciones de aluminio, caracterizado porque, anodizándose primero el artículo anodizado y un contraelectrodo sumergido en un baño acuoso ácido que contiene sales de metales capaces de colorear la capa anodizada, el artículo se anodiza en un electrolito que comprende de 12 a 24 por ciento en peso de ácido sulfúrico, de 1 a 4 por ciento en volumen de alcohol polihídrico de 3 a 6 átomos de carbono y de 1 a 4 por ciento en volumen de un ácido carboxílico orgánico que contiene por lo menos un grupo reactivo en la posición alfa, a una temperatura de 18-30ºC (65-85ºF) y a una densidad de corriente de 2,6-3,9 A dm2 (24-36 amperios/pie cuadrado), de modo que se obtenga una capa anodizada de 5 a 28 mim (0,2 a 1,1 milésimas de pulgadas).
