Abstract
PROCEDIMIENTO PARA ELECTRODEPOSITAR UN DEPOSITO DE CROMO SOBRE UN SUSTRATO CONDUCTOR DE LA ELECTRICIDAD. CONSISTE EN SUMERGIR EL SUSTRATO EN UN ELECTROLITO DE CROMO TRIVALENTE ACIDO ACUOSO, QUE CONTIENE CRB3, UN AGENTE COMPLEJANTE, HB PARA MANTENER EL PH EN ESCALA ACIDA Y UN AGENTE ADITIVO FORMADO POR IONES METALICOS PARA MANTENER LA CONCENTRACION DE CRB6 PARA LOGRAR ELECTRODEPOSITOS DE CROMO. EL SUSTRATO SE CARGA CATODICAMENTE Y EL CROMO SE DEPOSITA A DENSIDADES DE CORRIENTE ENTRE 0,05 Y 0,25 A/CM, A TEMPERATURAS ENTRE 15 Y 45JC Y PH ENTRE 2,5 Y 5,5 HASTA LOGRAR EL ESPESOR DESEADO. APLICACION COMO REVESTIMIENTOS PROTECTORES Y DECORATIVOS EN SUSTRATOS METALICOS.
