Abstract

UN METODO PARA TRATAR ELECTROLITICAMENTE UN CUERPO DE MATERIAL CONDUCTOR QUE CONSISTE EN COLOCAR EL MATERIAL A TRATAR EN UN ELECTROLITO OXIDANTE ACUOSO, HACER PASAR UNA CORRIENTE ELECTRICA A TRAVES DEL ELECTROLITO Y DEL MATERIAL A TRATAR Y ROCIAR EL ELECTROLITO CON GAS. EL MATERIAL A TRATAR SE COLOCA EN UNA CESTA QUE CONTIENE UNA ESTRUCTURA CONDUCTORA CON UN RECEPTACULO AISLANTE ACOPLADO EN ELLA, EN DONDE LA CESTA SE PUEDE INTRODUCIR EN Y SACAR DEL ELECTROLITO SEGUN SE DESEE. EL RECEPTACULO AISLANTE SE PUEDE RETIRAR DE LA ESTRUCTURA CONDUCTORA, Y LA ESTRUCTURA TIENE UN ELEMENTO DE RETENCION PARA RECIBIR EL RECEPTACULO AISLANTE. EL RECEPTACULO INCLUYE EN LA BASE UNAS PERFORACIONES PARA PERMITIR QUE EL ELECTROLITO ENTRE EN CONTACTO CON EL MATERIAL A TRATAR. EL ELECTROLITO SE ROCIA CON GAS EN LA REGION DONDE EL MATERIAL A TRATAR SE ENCUENTRA EN CONTACTO CON EL, EN DONDE EL GAS ES SUMINISTRADO A TRAVES DE UNA PLURALIDAD DE TUBOS (21, 22) QUE SE EXTIENDEN A TRAVES DEL ELECTROLITO POR DEBAJO DE LA BASE PERFORADA DEL RECEPTACULO AISLANTE. CADA TUBO TIENE UNA PLURALIDAD DE AGUJEROS DE SALIDA DEL GAS DIRIGIDOS HACIA EL MATERIAL A TRATAR.
