Abstract

METODO PARA LA OBTENCION, POR VIA ELECTROLITICA, SOBRE ALUMINIO ANODIZADO, DE UNA GAMA DE COLORES GRISES. EL METODO, BASADO EN LA APLICACION DE UN ANODIZADO, UN OPACIFICADO Y FINALMENTE UN COLOREADO ELECTROLITICO, SE CENTRA FUNDAMENTALMENTE EN ESTABLECER UN PERFECTO CONTROL INDEPENDIENTE DE LOS SEMICICLOS POSITIVOS Y NEGATIVOS DE LA TENSION APLICADA, A LO LARGO DE TODO EL PROCESO, PARA CONTROLAR A SU VEZ LA PRODUCCION DE HIDROGENO ATOMICO Y CONTROLAR EL ESPESOR DE LA PELICULA BARRERA. SE PREVEE LA UTILIZACION DE ELECTROLITOS CON UN CONTENIDO EN ACIDO SULFURICO INFERIOR A 200 GR.L., CON ADITIVOS A BASE DE COMPUESTOS ORGANICOS, CONCRETAMENTE ACIDOS DICARBOXILICOS, ALCOHOLES, ALDEHIDOS Y CETONAS, Y TENSOACTIVOS TANTO ANIOINICOS COMO NO IONICOS, ELECTROLITO UTILIZADO TANTO EN LA FASE DE OPACIFICADO COMO EN LA DE ANODIZADO.
