Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a process for making a grinding wheel for the squaring of ceramic, formed by a support body and an abrasive ring. The process does not involve costly workings on the body and on the ring and produces a light grinding wheel which, therefore, is more practical to be handled by the handling machine.
