Abstract
A method of processing a polycrystalline diamond body includes positioning an electrode near the polycrystalline diamond body such that a gap is defined between the electrode and the polycrystalline diamond body, the polycrystalline diamond body having a metallic material disposed in interstitial spaces defined within the polycrystalline diamond body. The method includes applying a voltage between the electrode and the polycrystalline diamond body, and passing a processing solution through the gap. The electrode is a cathode and the polycrystalline diamond body is an anode. An assembly for processing a polycrystalline diamond body includes the polycrystalline diamond body, an electrode positioned such that a gap is defined between the electrode and the polycrystalline diamond body, a processing solution passing through the gap such that the processing solution is in electrical communication with each of the polycrystalline diamond body and the electrode, and at least one power source.
