Abstract

METODO PARA OBTENER UN BAÑO DE ORO RESISTENTE. COMPRENDE LAS SIGUIENTES ETAPAS: 1) SE ELECTRODEPOSITA UN REVESTIMIENTO DE NIQUEL DUCTIL, SIN TENSION, SOBRE EL SUSTRATO, OBTENIDO A PARTIR DE UN BAÑO ELECTROPLASTICO QUE CONTIENE UNA SAL DE NIQUEL, UN ELECTROLITO SELECCIONADO DEL GRUPO FORMADO POR ACIDO BORICO, ACIDO CITRICO Y ACIDO ORTOFORMILBENCENOSULFONICO, UTILIZANDO COMO AGENTE HUMECTANTE UNA MEZCLA DE PERFLUORALQUILSULFONATOS DE POTASIO; 2) SE ELECTRODEPOSITA UN REVESTIMIENTO DE ORO ENDURECIDO CON UN METAL BASICO SOBRE EL SUSTRATO BAÑADO CON NIQUEL DUCTIL, OBTENIDO A PARTIR DE UN BAÑO ELECTROPLASTICO QUE CONTIENE UNA SAL DE ORO Y UN ELECTROLITO, Y POR ULTIMO, SE AÑADE AL REVESTIMIENTO DE ORO UNA SAL METALICA.
