Abstract

L'INVENTION DECRIT L'OBTENTION D'UN CORPS EN CARBURE DE SILICIUM DENSE, PRESENTANT AU MOINS DEUX PARTIES DONT LA TENEUR EN SI LIBRE DIFFERE. ON COMPACTE UN PREMIER MELANGE DE C ET DE CARBURE DE SILICIUM; ON COMPACTE UN SECOND MELANGE DE C ET DE CARBURE DE SILICIUM AU CONTACT DU PREMIER ET EN DES PROPORTIONS DIFFERENTES DE CELLES DU PREMIER MELANGE POUR FORMER UN CORPS A L'ETAT VERT COMPRENANT LES PREMIERE ET SECONDE PARTIES AINSI OBTENUES, ET L'ON SOUMET CE CORPS VERT A UN FRITTAGE AVEC REACTION EN PRESENCE DE SILICIUM FONDU. APPLICATION: OBTENTION D'UN CORPS DONT LA COUCHE SUPERFICIELLE CONTIENT NETTEMENT PLUS DE SI LIBRE QUE LE RESTE DE CE CORPS AFIN DE FORMER UNE ENVELOPPE PERIPHERIQUE POUR LES AUBES DU ROTOR D'UN TURBOMOTEUR, PAR EXEMPLE.
