Abstract

PROCEDE DE FRITTAGE SANS PRESSION DE MELANGES A BASE DE CARBURE DE SILICIUM DESTINES A L'OBTENTION D'UN PRODUIT DENSE DONT LE CARBURE DE SILICIUM CONSTITUANT LA MATIERE PREMIERE NE CONTIENT AUCUN AGENT DE DENSIFICATION TEL QUE DU BORE, DU BERYLLIUM OU DE L'ALUMINIUM. LA MATIERE PREMIERE CONSISTE EN UN MELANGE CONTENANT ESSENTIELLEMENT DU CARBURE DE SILICIUM PARTICULAIRE ET COMPRENANT EN GENERAL MOINS D'ENVIRON 10 ET DE PREFERENCE MOINS D'ENVIRON 6 EN POIDS DE CARBONE SOUS FORME ELEMENTAIRE OU SOUS FORME D'UNE SOURCE. LES MELANGES CONTIENNENT AUSSI DES QUANTITES FAIBLES D'AUTRES ADDITIFS TELS QUE DES LUBRIFIANTS, AGENTS TENSIO-ACTIFS OU AGGLUTINANTS QUI SONT DESTINES A CONTRIBUER A LA FORMATION D'UNE EBAUCHE DE COMPACT, OU DE FAIBLES QUANTITES D'AUTRES MATIERES CERAMIQUES, SELON LA NATURE DU PRODUIT FINAL DEVANT ETRE OBTENU. LES EBAUCHES DE COMPACT SONT FRITTEES SENSIBLEMENT SANS PRESSION DANS UNE ATMOSPHERE CONTENANT DU BORE, LE PRODUIT FRITTE AYANT UNE DENSITE D'AU MOINS 85 ET MEME SUPERIEURE A ENVIRON 90 DE LA DENSITE THEORIQUE DU CARBURE DE SILICIUM. APPLICATION A LA REALISATION DE PIECES DE TURBINES, POMPES OU ANALOGUES OU D'OUTILS.
