Abstract

CE PROCEDE CONCERNE LA FABRICATION D'UN OBJET A PARTIR D'UNE MATIERE SOUS FORME D'UNE POUDRE, PAR PRESSAGE ISOSTATIQUE D'UN CORPS PREFORME A PARTIR DE LA POUDRE AU MOYEN D'UN AGENT DE PRESSION GAZEUX, LE CORPS PREFORME ETANT ENTOURE D'UNE GAINE PERMEABLE AUX GAZ QUI SE TRANSFORME EN UNE GAINE IMPERMEABLE A L'AGENT DE PRESSION ET ENFERME LE CORPS PREFORME, APRES QUOI LE PRESSAGE ISOSTATIQUE EST EFFECTUE POUR LE FRITTAGE DU CORPS PREFORME. LA GAINE PERMEABLE AUX GAZ 15 EST TRANSFORMEE EN GAINE IMPERMEABLE A L'AGENT DE PRESSION, PENDANT QUE CETTE GAINE EST MISE EN CONTACT AVEC UN GAZ COMPRIME ET PENDANT QU'IL EST MAINTENU, DANS CE GAZ, UNE PRESSION AUSSI ELEVEE QUE LA PRESSION QUI REGNE DANS LE GAZ QUI SE TROUVE DANS LES PORES DU PRODUIT PREFORME 14.THIS PROCESS CONCERNS THE MANUFACTURE OF AN OBJECT FROM A MATERIAL IN THE FORM OF A POWDER, BY ISOSTATIC PRESSING OF A PREFORMED BODY FROM POWDER BY MEANS OF A GAS PRESSURE AGENT, THE PREFORMED BODY BEING SURROUNDED OF A SHEATH PERMEABLE TO GAS WHICH TRANSFORMS INTO A SHEATH IMPERMEABLE TO THE PRESSURE AGENT AND ENCLOSES THE PREFORMED BODY, AFTER ISOSTATIC PRESSING IS PERFORMED FOR FRITTING THE PREFORMED BODY. THE GAS PERMEABLE SHEATH 15 IS TRANSFORMED INTO A PRESSURE AGENT IMPERMEABLE SHEATH, WHILE THIS SHEATH IS PLACED IN CONTACT WITH A COMPRESSED GAS AND WHILE IT IS MAINTAINED IN THIS GAS, A PRESSURE AS HIGH AS THE PRESSURE WHICH IS MAINTAINED IN THIS GAS. REIGN IN THE GAS WHICH IS IN THE PORES OF THE PREFORMED PRODUCT 14.
