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.
