Abstract
A method of processing a polycrystalline diamond material includes exposing at least a portion of a polycrystalline diamond material to a processing solution, the polycrystalline diamond material including a metallic material disposed in interstitial spaces defined within the polycrystalline diamond material. The method includes exposing an electrode to the processing solution, applying a positive charge to the polycrystalline diamond material, and applying a negative charge to the electrode. An assembly for processing a polycrystalline diamond body includes a polycrystalline diamond body and an electrode that are in electrical communication with a volume of processing solution, and a power source configured to apply a positive charge to the polycrystalline diamond body and a negative charge to the electrode.
