Abstract

EMPLEANDOSE LAS ALEACIONES EN TRAZAS COMO ANODO Y COMO CATODO, Y SE INVIERTE LA POLARIDAD DE LA CORRIENTE DE ELECTROLISIS CON UNA FRECUENCIA ENTRE 0,005 Hz Y 5 Hz. LAS ALEACIONES CONTIENEN Co, Ni, Cr o Al COMO COMPONENTES PRINCIPALES; Y Ta, Re, W, Mo, Hf o Pt COMO COMPONENTES SECUNDARIOS. LA LIXIVIACION SE LLEVA A CABO CON UNA CORRIENTE CONSTANTE ENTRE 2 V y 6 V, Y SE EMPLEA UN ACIDO INORGANICO LIBRE DE OXIGENO COMO ELECTROLITO
