Abstract

Elément ayant une meilleure résistance à la dégradation thermique. Il comprend : a) des particules liées entre elles choisies dans le groupe comprenant le diamant et le nitrure de bore cubique, ces particules représentant entre 70 et 95 % en volume environ de cet élément, et, b) un réseau intercommunicant de pores vides dispersés à travers tout l'élément et délimités par les particules, ces pores constituant environ 5 à 30 % en volume de l'élément, et entre environ 0,05 et 3 % en volume d'une phase métallique constituée d'un auxiliaire de frittage pour la masse de particules abrasives choisies. Application aux outils abrasifs.
