A method of manufacturing a diamond sintered body includes the steps of preparing diamond powder having a particle size within the range of from 0.1 to 10 µm, coating the surface of each particle of the diamond powder with a sintering assistant agent including Pd within a range of from 0.01 to 40 percent by weight and at least one of an iron family metal as the remaining part, and sintering the coated diamond powder in liquid-phase under high pressure and high temperature conditions, so that a diamond sintering body having high strength and high wear-resistance containing 80 to 96 percent by volume of diamond particles can be obtained.
Méthode de fabrication d'un corps fritté diamantaire comprenant les étapes suivantes : préparer une poudre de diamant dont la dimension des particules est de l'ordre de 0,1 à 10 micromètres; revêtir la surface de chaque particule de poudre de diamant d'un agent contribuant au frittage contenant du Pd dans une proportion de 0,01 à 40 % en poids et au moins un métal de la famille pour la partie restante, et fritter la poudre de diamant revêtue en phase liquide à pression et à température élevées, pour qu'il soit possible d'obtenir un corps fritté diamantaire possédant une grande résistance et une forte résistance à l'usure renfermant de 80 à 96 % en volume de particules de diamant.
