Abstract

EN UN PROCESO DE APLICACION DE REVESTIMIENTOS DE CONVERSION SOBRE SUPERFICIES METALICAS DE ALUMINIO, CINC Y SUS ALEACIONES CON AYUDA DE SOLUCIONES ALCALINAS CON CROMO VI Y CROMO III SE USA UNA SOLUCION QUE CONTIENE AL MENOS 20 PPM, PREFERENTEMENTE DE 100 A 500 PPMCROMO III DISUELTO COMO CONSECUENCIA DE LA ADICION DE UN COMPLEXIFICADOR PARA CROMO III, EN ESPECIAL ACIDO HIDROXICARBOXILICO Y/O ACIDO AMINOCARBOXILICO. EL CROMO III SE APLICA COMO NITRATO, SULFATO, FOSFATO Y/O ACETATO. EL CONTENIDO EN CROMO IV DEBERIA SER DE 8 A 75 PPM, PREFERENTEMENTE DE 15 A 60 PPM, Y EL PH DE LA SOLUCION DEBERIA SER AL MENOS 12, PREFERENTEMENTE 12,5.
