Abstract:
In an embodiment, a method of fabricating a polycrystalline diamond compact is disclosed. The method includes sintering a plurality of diamond particles in the presence of a metal-solvent catalyst to form a polycrystalline diamond body; leaching the polycrystalline diamond body to at least partially remove the metal-solvent catalyst therefrom, thereby forming an at least partially leached polycrystalline diamond body; and subjecting an assembly of the at least partially leached polycrystalline diamond body and a cemented carbide substrate to a high-pressure/high-temperature process at a pressure to infiltrate the at least partially leached polycrystalline diamond body with an infiltrant. The pressure of the high-pressure/high-temperature process is less than that employed in the act of sintering of the plurality of diamond particles.

Claim (Index 25):
A polycrystalline diamond compact, comprising:\n a polycrystalline diamond table, at least an unleached portion of the polycrystalline diamond table including:\n a plurality of diamond grains bonded together via diamond-to-diamond bonding to define interstitial regions, the plurality of diamond grains exhibiting an average grain size of about 10 \u03bcm to about 18 \u03bcm; and \n a catalyst including cobalt, the catalyst occupying at least a portion of the interstitial regions; \n wherein the unleached portion of the polycrystalline diamond table exhibits a coercivity of about 115 Oe to about 250 Oe; \n wherein the unleached portion of the polycrystalline diamond table exhibits a specific permeability of about 0.060 G\u00b7cm 3 /g\u00b7Oe to about 0.090 G\u00b7cm 3 /g\u00b7Oe; and \n a substrate bonded to the polycrystalline diamond table along an interfacial surface, the interfacial surface exhibiting a substantially planar topography; wherein a lateral dimension of the polycrystalline diamond table is about 1.3 cm to about 1.9 cm.
