Patent ID: 8764864

Claim:
A polycrystalline diamond compact, comprising: a substrate; and a polycrystalline diamond table including an interfacial surface bonded to the substrate, a generally opposing upper surface, and at least one lateral surface extending between the interfacial surface and the upper surface, the polycrystalline diamond table including a plurality of diamond grains exhibiting diamond-to-diamond bonding therebetween and defining a plurality of interstitial regions, the polycrystalline diamond table further including: a plurality of first thermally-stable regions circumferentially spaced from each other and extending inwardly from the upper surface and the at least one lateral surface to a selected depth, the plurality of first thermally-stable regions including a copper-containing material disposed in at least a first portion of the plurality of interstitial regions; and a second region extending inwardly from the substrate and disposed between the plurality of first thermally-stable regions, the second region having a metallic material disposed in at least a second portion of the plurality of interstitial regions.
