Abstract

PROCEDE UTILISANT DES PRESSIONS RELATIVEMENT PEU ELEVEES. IL CONSISTE A PLACER DANS UNE COUPELLE 13 UNE MASSE D'ALLIAGE SOLIDE EUTECTIFERE, RICHE EN SILICIUM 12, UNE MASSE DE CRISTAUX DE DIAMANT 13 ET UN SUBSTRAT DE CARBURE OU NITRURE DE SILICIUM 14; A DISPOSER L'ENSEMBLE DANS UN MILIEU EN POUDRE DE TRANSMISSION DE PRESSION; A EFFECTUER UN PRESSAGE A FROID DE L'ENSEMBLE POUR OBTENIR UN SYSTEME STABILISE EN DIMENSION, A PRESSER A CHAUD LE SYSTEME STABILISE EN DIMENSION POUR FAIRE S'INFILTRER L'ALLIAGE RICHE EN SILICIUM DANS LA MASSE DE DIAMANT ET A L'INTERFACE ENTRE LA MASSE DE DIAMANT ET LE SUBSTRAT, A MAINTENIR UNE PRESSION SUFFISANTE PENDANT LE REFROIDISSEMENT POUR CONSERVER LA STABILITE DE DIMENSION ET A RECUPERER LE COMPOSITE FORME. APPLICATION A LA FABRICATION D'OUTILS DE COUPE.PROCESS USING RELATIVELY LOW-HIGH PRESSURES. IT CONSISTS OF PLACING IN A CUP 13 A MASS OF SOLID EUTECTIFIER ALLOY, RICH IN SILICON 12, A MASS OF DIAMOND CRYSTALS 13 AND A SUBSTRATE OF CARBIDE OR SILICON NITRIDE 14; TO DISPOSE OF THE ASSEMBLY IN A PRESSURE TRANSMISSION POWDER MEDIUM; A COLD PRESSING OF THE ASSEMBLY TO OBTAIN A SYSTEM STABILIZED IN DIMENSION, A HOT PRESSING THE SYSTEM STABILIZED IN DIMENSION TO ENSURE THE SILICON-RICH ALLOY INTO THE DIAMOND GROUND AND AT THE INTERFACE BETWEEN THE DIAMOND MASS AND THE SUBSTRATE, TO MAINTAIN SUFFICIENT PRESSURE DURING COOLING TO KEEP SIZE STABILITY AND RECOVER THE COMPOSITE FORM. APPLICATION TO THE MANUFACTURING OF CUTTING TOOLS.
