Superabrasive elements may be produced by method includes providing a superabrasive element including a polycrystalline diamond table that includes a metallic material disposed in interstitial spaces defined within the polycrystalline diamond table. The polycrystalline diamond table includes a superabrasive face and a superabrasive side surface extending around an outer periphery of the superabrasive face. The method also includes leaching the metallic material from at least a volume of the polycrystalline diamond table to produce a leached volume in the polycrystalline diamond table by (1) exposing at least a portion of the polycrystalline diamond table to a processing solution, (2) exposing an electrode to the processing solution, and (3) applying a charge to the electrode.

Embodiments relate to polycrystalline diamond compacts (PDCs), methods of fabricating PDCs, and applications for such PDCs. In an embodiment, a method includes providing an at least partially leached polycrystalline diamond (PCD) body. A residual amount of acid may remain in and/or on the at least partially leached PCD body. The method further includes removing and/or neutralizing at least some of the residual amount of acid from the at least partially leached PCD body and/or a substrate to which the at least partially leached PCD body is attached.

In an embodiment, a polycrystalline diamond compact includes a substrate, and a polycrystalline diamond (PCD) table bonded to the substrate and including an exterior working surface, at least one lateral surface, and a chamfer extending between the exterior working surface and the at least one lateral surface. The PCD table includes bonded diamond grains defining interstitial regions. The PCD table includes a first region adjacent to the substrate and a second leached region adjacent to the first region and extending inwardly from the exterior working surface to a selected depth. At least a portion of the interstitial regions of the first region include an infiltrant disposed therein. The interstitial regions of the second leached region are substantially free of metal-solvent catalyst. The second region is defined by the exterior working surface, the lateral surface, the chamfer, and a generally horizontal boundary located below the chamfer.

A polycrystalline diamond compact (PDC), which is attached or bonded to a substrate to form a cutter for a drill bit, is comprised of sintered polycrystalline diamond interspersed with a seed material which has a hexagonal close packed (HCP) crystalline structure. A region of the sintered polycrystalline diamond structure, near one or more of its working surfaces, which has been seeded with an HCP seed material prior to sintering, is leached to remove catalyst. Selectively seeding portions or regions of a sintered polycrystalline diamond structure permits differing leach rates to form leached regions with differing distances or depths and geometries.
