Abstract

PROCEDIMIENTO PARA DEPOSITAR CROMO ELECTROLITICAMENTE EN UN SUSTRATO CONDUCTOR A PARTIR DE UN ELECTROLITO DE CROMO TRIVALENTE, DE FORMA QUE SE INHIBE LA FORMACION DE IONES DE CROMO HEXAVALENTES PERJUDICIALES EN ELECTROLITO.COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE PROPORCIONA UN BAÑO COMPUESTO POR UN ELECTROLITO ACIDO ACUOSO QUE CONTIENE IONES DE CROMO TRIVALENTES Y UN AGENTE COMPLEJANTE; SEGUNDA, SE SUMERGE UN ANODO EN DICHO BAÑO POR LO MENOS EN UNA PARTE DE LA SUPERFICIE QUE ESTA COMPUESTA DE FERRITA; TERCERA, AE SUMERGE UN SUSTRATO QUE ES ELECTRODEPOSITADOEN EL BAÑO; CUARTA, SE ELECTRIFICA ANODICAMENTE EL ANODO Y SE ELECTRIFICA CATODICAMENTE EL SUSTRATO; Y POR ULTIMO, SE HACE PASAR CORRIENTE A TRAVES DEL BAÑO PARA EFECTUAR LA ELECTRODEPOSICION DE CROMO EN EL SUSTRATO.
