Abstract

EN LA PRESENTE INVENCION SE DA UN METODO PARA OBTENER UN CUERPO DE CERAMICA AUTOSOPORTANTE POR OXIDACION DE UN METAL ORIGINAL PARA FORMAR UN MATERIAL CERAMICO POLICRISTALINO QUE CONSTA ESENCIALMENTE DEL PRODUCTO DE LA REACCION DE OXIDACION DE DICHO METAL ORIGINAL CON UN OXIDANTE, QUE INCLUYE UN OXIDANTE EN FASE DE VAPOR, Y OPCIONALMENTE UNO O MAS CONSTITUYENTES METALICOS. EL METODO COMPRENDE LAS ETAPAS DE DOTAR AL MENOS UNA PORCION DE DICHO METAL ORIGINAL CON UN DISPOSITIVO DE BARRERA PARA ESTABLECER AL MENOS UNA SUPERFICIE DEL CUERPO CERAMICO Y CALENTAR DICHO METAL ORIGINAL A UNA TEMPERATURA POR ENCIMA DE SU PUNTO DE FUSION PERO POR DEBAJO DEL PUNTO DE FUSION DEL PRODUCTO DE REACCION DE OXIDACION PARA FORMAR UN CUERPO DE METAL FUNDIDO. A ESA TEMPERATURA EL METAL FUNDIDO REACCIONA CON EL OXIDANTE, FORMANDO ASI EL PRODUCTO DE LA REACCION OXIDACION. AL MENOS UNA PORCION DEL PRODUCTO DE REACCION DE OXIDACION SE MANTIENE EN CONTACTO CON EL METAL FUNDIDO Y EL OXIDANTE, Y ENTRE ELLOS, PARA TRANSPORTAR EL METAL FUNDIDO A TRAVES DEL PRODUCTO DE REACCION DE OXIDACION HACIA EL DISPOSITIVO DE BARRERA Y ENTRA EN CONTACTO CON EL OXIDANTE DE MODO QUE SE SIGUE FORMANDO EL PRODUCTO DE REACCION DE OXIDACION ENTRE LAS CARAS DEL OXIDANTE Y DEL PRODUCTO DE REACCION DE OXIDACION PREVIAMENTE FORMADO, DEJANDO OPCIONALMENTE METAL DISPERSO A TRAVES DEL MATERIAL POLICRISTALINO. LA REACCION SE CONTINUA HASTA EL DISPOSITIVO DE BARRERA PARA PRODUCIR UN CUERPO CERAMICO QUE TIENE LA SUPERFICIE ESTABILIZADA POR EL DISPOSITIVO DE BARRERA. SE FORMA UN COMPUESTO SUPERPONIENDO UNA BARRERA SOBRE UN MATERIAL DE RELLENO, TAL COMO UNA PREFORMA, E INFILTRANDO EL MATERIAL DE RELLENO CON LA MATRIZ CERAMICA POLICRISTALINA FORMADA HASTA EL DISPOSITIVO DE BARRERA.
