Abstract

L'invention concerne un procédé de fabrication de pièces ou organes en carbure fritté Selon l'invention, on forme à la presse une ébauche agglomérée 13 en poudre vierge de carbure fritté à base de carbure de tungstène, et une ébauche agglomérée 12 en poudre de carbure fritté régénérée à partir de déchets de produits en carbure fritté, on réunit entre elles ces deux ébauches et on les fritte ensemble pour produire une pièce unitaire 14 qui répond à toutes les conditions exigées mais est d'un coût réduit. L'invention est applicable, notamment, à la fabrication de cylindres de laminoir, de bouchons d'obturation, de filières, etc.
