Abstract

EL PROCESO DE RECUBRIMIENTO DE ALUMINIO DE UNA CHAPA DE ACERO MAGNETICO CON GRANOS ORIENTADOS HABIENDO SUFRIDO AL MENOS UN LAMINADO EN FRIO, AL MENOS UN RECOCIDO INTERMEDIARIO BAJO UNA ATMOSFERA DE HIDROGENO, SEGUIDOS DE UN RECOCIDO DE DESCARBURACION, LAS IMPUREZAS DE LA CHAPA ESTAN ENTONCES EN SU ESTADO DE RECRISTALIZACION PRIMARIO, ESTA CARACTERIZADO PORQUE SE EFECTUA UN SEDIMENTO DE ALUMINIO SOBRE SUSODICHA CHAPA ENTRE DOS ETAPAS DE UN RECOCIDO FINAL EN CUYA PRIMERA ETAPA REALIZA UNA RECRISTALIZACION SECUNDARIA PARCIAL O TOTAL DE LAS IMPUREZAS DE LA CHAPA Y EN CUYA SEGUNDA ETAPA PERMITE LA DIFUSION DEL ALUMINIO Y LA ELIMINACION DE LAS IMPUREZAS.
