Beschreibung
Zusammenfassung:	An ultra-hard composite material comprises a mass of diamond grains exhibiting inter-granular bonding and a binder. The binder comprises a material of the formula Mn+1AXn. M is one or more elements selected from the group consisting of Sc, Ti, V, Cr, Zr, Nb, Mo, Hf and Ta. A comprises at least one element selected from the group consisting of Al, Si, Sb, Bi, P, S, Se, Te, Po, Ga, Ge, As, Cd, In, Sn, Tl and Pb. X is carbon or nitrogen or a combination of carbon and nitrogen, n is about 1, 2 or 3. Methods of making the ultra-hard composite material are also provided. La présente invention a pour objet un matériau composite ultra dur comprenant une masse de grains de diamant présentant une liaison intergranulaire et un liant. Le liant comprend un matériau de la formule Mn+1AXn. M est un ou plusieurs éléments choisis dans le groupe comprenant Sc, Ti, V, Cr, Zr, Nb, Mo, Hf et Ta. A comprend au moins un élément choisi dans le groupe comprenant Al, Si, Sb, Bi, P, S, Se, Te, Po, Ga, Ge, As, Cd, In, Sn, Tl et Pb. X est le carbone ou l'azote ou une combinaison de carbone et d'azote, n est environ égal à 1, 2 ou 3. La présente invention a également pour objet des procédés de fabrication du matériau composite ultra dur.
