Abstract

LA INVENCION SE REFIERE A UN METODO RELATIVO A LA FABRICACION POR PULVIMETALURGIA DE UN CUERPO QUE TIENE UN ORIFICIO PASANTE, POR EJEMPLO UNA PIEZA EN TOSCO DE UNA HERRAMIENTA VACIADA O UN TUBO DE PARED GRUESA. LA PROPIEDAD CARACTERISTICA DE ESTE METODO ES QUE EN UNA CAPSULA EXTERIOR SE HA DISPUESTO UN TUBO (6) QUE TIENE PRACTICAMENTE LA MISMA LONGITUD QUE LA CAPSULA, DE TAL FORMA QUE EL TUBO SE EXTIENDE PRACTICAMENTE A TRAVES DE TODA LA LONGITUD DE LA CAPSULA, QUE EN EL TUBO SE HA DISPUESTO UN NUCLEO (5) QUE TAMBIEN SE EXTIENDE A TRAVES DE LA CAPSULA Y DE TODA LA LONGITUD DEL TUBO, QUE EL ESPACIO ENTRE EL TUBO (6) Y EL LADO INTERIOR DE LA CAPSULA (1) SE HA LLENADO CON UN POLVO METALICO (9) QUE DEBE CONFORMAR EL CUERPO DESEADO, QUE EL ESPACIO (10) EN EL TUBO (6) ENTRE EL NUCLEO (5) Y EL LADO INTERIOR DEL TUBO SE HA LLENADO CON UN POLVO NO METALICO (1), QUE LA CAPSULA ESTA CERRADA HERMETICAMENTE, Y QUE LA CAPSULA CERRADA Y SU CONTENIDO SE SOMETEN A UNA COMPACTACION ISOSTATICA CALIENTE A UNATEMPERATURA SUPERIOR A 1000 {SUP,O}C, DE TAL FORMA QUE EL POLVO METALICO SE COMPACTA HASTA UNA DENSIDAD TOTAL.
