Abstract

METODO PARA FABRICAR UN OBJETO DE MATERIAL EN POLVO POR COMPRESION ISOSTATICA DE UN CUERPO (10), PREFORMADO A PARTIR DE MATERIAL EN POLVO, CON LO QUE EL CUERPO PREFORMADO SE RODEA DE UNA CUBIERTA (16) QUE POR LO MENOS EN SU MAYOR PARTE SE PASA A FASE FUNDIDA, ANTES DE QUE SE LLEVE A LA COMPRESION ISOSTATICA, MIENTRAS SE SINTERIZA EL POLVO. COMO MATERIAL DE CUBIERTA SE UTILIZA VIDRIO O UN MATERIAL QUE FORMA VIDRIO CUANDO SE CALIENTA Y QUE CONTIENE 48-52 % EN PESO DE B2O3, 46-50 % EN PESO DE SIO2 Y 1,5-2,5 % EN PESO DE AL2O3. ESTE SE PUEDE EXTRAER DEL OBJETO ACABADO POR AGUA O VAPOR DE AGUA, Y TIENE UN COEFICIENTE DE DILATACION TERMICA BAJO A TEMPERATURAS INFERIORES A LA TEMPERATURA DE FUSION DEL VIDRIDO. PARA IMPEDIR LA PENETRACION DEL VIDRIO FUNDIDO DE LA CUBIERTA EN EL CUERPO PREFORMADO, SE PUEDE ADAPTAR UNA CAPA BARRERA (18) SOBRE EL CUERPO PREFORMADO DENTRO DE LA CUBIERTA.
