发明名称 SYSTEMS AND METHODS FOR VAPOR PRESSURE LEACHING POLYCRYSTALLINE DIAMOND CUTTER ELEMENTS
摘要 <p>A system for leaching a polycrystalline diamond (PCD) cutter element having a PCD table and a substrate, the system including a housing having an open first end and a closed second end and a lid removably and sealingly attached the first end of the housing. The housing and the lid define an inner chamber extending between the first end and the second end, and the inner chamber is configured to receive and hold a volume of liquid acid therein. In addition, the system includes a cutter element holder disposed within the inner chamber, wherein the PCD cutter element is suspended above the volume of liquid acid in the inner chamber with the holder.</p>
