Abstract

SISTEMAS DE PROTECCION CONTRA LA CORROSION QUE HACEN USO DE UNA BARRERA (2), LA CUAL SE COLOCA ENTRE UN SUSTRATO (3) CORROIBLE Y UN CONTRAELECTRODO (2). LA BERRERA PUEDE PROPORCIONAS UNA DISTRIBUCION DE CORRIENTE MAS UNIFORME SOBRE EL SUSTRATO Y/O PERMITIR QUE EL CONTRAELECTRODO SEA MAS FACIL DE MANTENER O DE REEMPLAZAR Y/O REDUCIR LA VELOCIDAD A LA QUE LA DENSIDAD DE CORRIENTE A LO LARGO DE UN ELECTRODO ALARGADO VARIA CON LA DISTANCIA A LA FUENTE DE ALIMENTACION Y/O PROPORCIONAR UN MEDIO CONTROLADO ALREDEDOR DEL ELECTRODO, PARA MEJORAR SU EFICACIA.
