Abstract

L'invention porte sur l'utilisation d'une poudre de Co renforcée par une dispersion d'oxyde comme liant dans la fabrication d'outils diamantés par frittage sous pression. L'invention porte sur un procédé de fabrication de poudre de Co renforcée par une dispersion d'oxyde, l'oxyde étant fin et distribué de façon homogène dans la poudre de Co. La présence de l'oxyde évite une croissance de grain excessive pendant le frittage aux températures élevées, maintenant la dureté suffisamment élevée.
