Title (EN) PRE-ALLOYED COPPER CONTAINING POWDER, AND ITS USE IN THE MANUFAC TURE OF DIAMOND TOOLS
(FR) POUDRE PRE-ALLIEE A BASE DE CUIVRE, ET UTILISATION DE CETTE POUDRE DANS LA FABRICATION D'OUTILS EN DIAMANT
Abstract:
(EN) The present invention relates to the use of a pre-alloyed powder as a binder in the manufacture of diamond tools by hot sintering. This powder is characterized in that it has an average particle size of less than 10 $g(m)m as measured with the Fisher SSS and loss of mass by reduction in hydrogen of less than 2 % as measured according to the standard ISO 4491-2:1989 and in that it contains, in % by weight, up to 40 % of cobalt, up to 50 % of nickel, from 5 to 80 % of iron and from 5 to 80 % of copper; the other components in the powder consist of unavoidable impurities.
(FR) La présente invention a pour objet l'utilisation d'une poudre pré-alliée comme liant dans la fabrication d'outils en diamant par frittage à chaud. Cette poudre se caractérise en ce qu'elle présente une taille de particule moyenne inférieure à 10 $g(m)m, mesurée avec le sous-tamiseur de Fisher et une perte de masse par réduction d'hydrogène de moins de 2 %, mesurée selon la norme ISO 4491-2:1989. En outre, cette poudre contient, en pourcentage en poids, jusqu'à 40 % de cobalt, 50 % de nickel, 5 à 80 % de fer, et de 5 à 80 % de cuivre. Les autres composants de la poudre sont des impuretés inévitables.
