Abstract

UN METODO PARA LA FABRICACION DE POLVOS DE CARBURO METALICO INCLUYE EL CALENTAMIENTO DE UNA MEZCLA DE REACTANTES SOLIDOS NO ESTATICOS DE UN OXIDO METALICO Y UNA FUENTE DE CARBONO A TEMPERATURA ELEVADA LA CUAL ES SUFICIENTE PARA PROVOCAR AL MENOS LA CARBURIZACION PARCIAL DE LA MEZCLA. EL CALENTAMIENTO REALIZADO EN UN ATMOSFERA NO REDUCTORA QUE TIENE UNA PRESION TOTAL DE AL MENOS UNA ATMOSFERA DURANTE UN TIEMPO SUFICIENTE PARA FORMAR UNA MEZCLA PARCIALMENTE CARBURIZADA. LA FUENTE DE CARBONO ES EMPLEADA A UN NIVEL EL CUAL ES MENOR QUE LA CANTIDAD ESTEQUIOMETRICA NECESITADA PARA PRODUCIR EL CARBURO METALICO. EL METODO PUEDE ADEMAS INCLUIR LA MEZCLA DE UN NIVEL SUFICIENTE DE UNA FUENTE DE CARBONO A LA MEZCLA PARCIALMENTE CARBURIZADA PARA FORMAR UNA MEZCLA AJUSTADA QUE TIENE UN CONTENIDO TOTAL EN CARBONO DE LA CANTIDAD ESTEQUIOMETRICA NECESITADA PARA FABRICAR EL CARBURO METALICO Y CARBURIZAR LA MEZCLA AJUSTADA EN UNA ATMOSFERA QUE CONTIENE HIDROGENO A UNA SEGUNDA TEMPERATURA ELEVADA LA CUAL ES SUFICIENTE PARA PROVOCAR QUE LA MEZCLA AJUSTADA FORMA EL CARBURO METALICO QUE TIENE UN TAMAÑO DE PARTICULA DE MENOS DE 0.2 MICROMETROS DE DIAMETRO.
