    Abstract: A method of characterizing a quality of a polycrystalline diamond compact (PDC) cutter includes obtaining a PDC cutter that includes a leached layer and an unleached layer. The unleached layer is positioned adjacent to the leached layer, and the leached layer has at least a portion of a catalyst material removed from therein. The method further includes measuring capacitance values of the PDC cutter at multiple frequencies of an electrical signal provided to the PDC cutter by a capacitance measuring device to measure the capacitance values of the PDC cutter. The method also includes characterizing a quality of the PDC cutter based on a lowest capacitance value from among the capacitance values. Each capacitance value of the capacitance values is measured at a respective frequency of the multiple frequencies of the electrical signal.

    Abstract: A catalyst removal apparatus and method for removing catalyst from a polycrystalline cutter. The cutter includes a substrate and a cutting table. The apparatus includes a tank forming a cavity therein, an electrolyte fluid occupying the cavity, the cutter, a covering surrounding at least a portion of the cutter's sidewall and extending from at least the substrate's top surface towards the bottom surface, a cathode submersed within the fluid, and a power source. The cutting table is submersed within the fluid and positioned near the cathode, thereby forming a gap therebetween. The power source is coupled to the cutter and the cathode and electrolyzes the fluid to react with the catalyst in the cutting table to produce a salt. The salt dissolves in the fluid and is removed from the cutter. Optionally, a transducer is sonically coupled to the cutter and emits vibrations to remove salt from the cutting table.

The upper portion is coupled to the second end. The sensor is positioned within the second cavity. In some embodiments, the apparatus includes a rod coupled to the lower portion. The rod has a lower acoustic impedance than the sensor holder, thereby allowing sound waves to pass through the sensor holder and not be reflected back into the sensor.
