POLYCRYSTALLINE DIAMOND COMPACTS HAVING INTERSTITIAL DIAMOND GRAINS AND METHODS OF MAKING THE SAME
Polycrystalline diamond compacts having interstitial diamonds and methods of forming polycrystalline diamond compact shaving interstitial diamonds with a quench cycle are described herein. In one embodiment, a polycrystalline diamond compact includes a substrate and a polycrystalline diamond body attached to the substrate. The polycrystalline diamond body includes a plurality of inter-bonded diamond grains that are attached to one another in an interconnected network of diamond grains and interstitial pockets between the inter-bonded diamond grains, and a plurality of interstitial diamond grains that are positioned in the interstitial pockets. Each of the plurality of interstitial diamond grains are attached to a single diamond grain of the interconnected network of diamond grains or other interstitial diamond grains.
L'invention concerne des compacts de diamants polycristallins ayant des diamants interstitiels, et des procédés de formation d'un compact de diamants polycristallins arasant des diamants interstitiels selon un cycle de trempe. Dans un mode de réalisation, un compact de diamants polycristallins comprend un substrat et un corps de diamants polycristallins fixé au substrat. Le corps de diamants polycristallins comprend une pluralité de grains de diamants reliés entre eux qui sont fixés les uns aux autres dans un réseau interconnecté de grains de diamants et de poches interstitielles entre les grains de diamants reliés, et une pluralité de grains de diamants interstitiels qui sont positionnés dans les poches interstitielles. Chaque grain de la pluralité de grains de diamants interstitiels est fixé à un seul grain de diamants du réseau interconnecté de grains de diamants ou à d'autres grains de diamants interstitiels.
