Abstract

PROCEDE DE FABRICATION D'UN OBJET A PARTIR D'UNE MATIERE CERAMIQUE OU METALLIQUE PAR PRESSAGE ISOSTATIQUE. UNE POUDRE DE CETTE MATIERE EST RENFERMEE DANS UN ENROBAGE DE VERRE QUI EST RENDU IMPERMEABLE AUX GAZ AVANT DE PROCEDER AU PRESSAGE ISOSTATIQUE AVEC FRITTAGE DE LA POUDRE. LA POUDRE EST ENSUITE INTRODUITE DANS LA CAVITE DE MOULAGE D'UN MOULE EN POUDRE DE VERRE 10, CETTE CAVITE DE MOULAGE CORRESPONDANT A L'OBJET A FABRIQUER. APRES QUOI LA CAVITE DE MOULAGE 11 EST RECOUVERTE DE VERRE, QUI FORME AVEC LE MOULE UN ENROBAGE POUR LA POUDRE DE MATIERE CERAMIQUE OU METALLIQUE. LA MATIERE D'ENROBAGE, QUE L'ON PLACE AVEC LA POUDRE DANS UN RECIPIENT QUI RESISTE A LA TEMPERATURE DE FRITTAGE, EST TRANSFORMEE EN UNE MASSE FONDUE QUI A UNE SURFACE DELIMITEE PAR LES PAROIS DU RECIPIENT, SURFACE SOUS LAQUELLE LA MATIERE SE TROUVE DANS LA CAVITE DE MOULAGE, ET ON APPLIQUE UNE PRESSION NECESSAIRE AU PRESSAGE ISOSTATIQUE SUR LA MASSE FONDUE PAR UN MOYEN DE PRESSION SOUS FORME DE GAZ. APPLICATION: FABRICATION D'OBJETS A PARTIR D'UNE MATIERE CERAMIQUE OU METALLIQUE TELS QUE ROUES DE TURBINE, FRAISES, ETC.METHOD OF MANUFACTURING AN OBJECT FROM A CERAMIC OR METAL MATERIAL BY ISOSTATIC PRESSING. A POWDER OF THIS MATERIAL IS CONTAINED IN A GLASS COATING WHICH IS MADE IMPERMEABLE TO GAS BEFORE PROCEEDING TO ISOSTATIC PRESSING WITH SINTING OF THE POWDER. THE POWDER IS THEN INTRODUCED INTO THE MOLDING CAVITY OF A GLASS POWDER MOLD 10, THIS MOLDING CAVITY CORRESPONDING TO THE OBJECT TO BE MANUFACTURED. AFTER WHAT, THE MOLDING CAVITY 11 IS COVERED WITH GLASS, WHICH WITH THE MOLD FORM A COATING FOR THE POWDER OF CERAMIC OR METAL MATERIAL. THE COATING MATERIAL, WHICH IS PLACED WITH THE POWDER IN A CONTAINER THAT RESISTS TO THE SINTERING TEMPERATURE, IS TRANSFORMED INTO A MELT MASS WHICH HAS A SURFACE DELIMITED BY THE WALLS OF THE CONTAINER, SURFACE UNDER WHICH THE MATERIAL IS LOCATED IN THE MOLDING CAVITY, AND A PRESSURE NECESSARY FOR ISOSTATIC PRESSING IS APPLIED TO THE MELT MASS BY A MEANS OF PRESSURE IN THE FORM OF GAS. APPLICATION: MANUFACTURING OF OBJECTS FROM A CERAMIC OR METAL MATERIAL SUCH AS TURBINE WHEELS, CUTTERS, ETC.
