Abstract

PROCEDIMIENTO PARA LA FORMACION DE UN DEPOSITO ELECTROGALVANICO DE CROMO SOBRE UN SUSTRATO CONDUCTOR DE LA ELECTRICIDAD. CONSISTE EN SUMERGIR EL SUSTRATO DE UN ELECTROLITO ACUOSO ACIDO DE CROMO TRIVALENTE EN CONCENTRACION 0,2-0,8% MOLAR, QUE CONTIENE ADEMAS UN AGENTE COMPLEJANTE, IONES HALURO Y AMONIO, UN REGULADOR DE PH PARA MANTENERLO ENTRE 2,5 Y 5,5, Y UN AGENTE REDUCTOR, CONSTITUIDO POR IONES VANADIO; Y APLICAR UNA CARGA CATODICA PARA REDUCIR LOS IONES CROMO A CROMO METALICO HASTA OBTENER UN DEPOSITO DE ESPESOR DESEADO. TIENE APLICACIONES PARA RECUBRIMIENTOS PROTECTORES Y DECORATIVOS SOBRE SUSTRATOS METALICOS.
