Abstract
SE EXPONE UN PROCESO DE DECAPADO DEL ACERO INOXIDABLE, EN EL QUE SE UTILIZA UNA SOLUCION DE DECAPADO QUE CONTIENE IONES DE HF Y FE 3+ COMO COMPONENTES ESENCIALES, Y EN DONDE LA OXIDACION EN FE 3+ DEL FE 2+ FORMADO DURANTE EL PROCESO, A FIN DE MANTENER LA CONCENTRACION DE FE 3+ EN EL VA LOR PREDETERMINADO, SE REALIZA ELECTROLITICAMENTE, SOMETIENDO LA SOLUCION DE DECAPADO, TAL COMO ESTA, A UN PROCESO DE OXIDACION EN UNA CUBETA ELECTROLITICA EQUIPADA CON UN ANODO REALIZADO DE MATERIALES INALTERABLES ELEGIDOS ENTRE EL GRAFITO, EL CARBON GRANULAR, EL PLOMO, Y CON CATODOS REALIZADOS CON ACERO INOXIDABLE, GRAFITO U OTROS MATERIALES INALTERABLES, TRABAJANDO DICHA CUBETA CON UNA TENSION APLICADA DE 1 A 8 V, Y CON UNA DENSIDAD DE CORRIENTE ANODICA SITUADA ENTRE 0,4 Y 15 -A/DM 2 .
