Abstract
A system for producing thermally stable cutting elements may include a heat source, a pressure vessel, at least one polycrystalline diamond body attached to a carbide substrate, and a leaching agent is disclosed, wherein the heat source includes a container comprising at least one receiving mechanism and at least one retention mechanism, and wherein the carbide substrate is disposed in the at least one receiving mechanism of the pressure vessel, and wherein the leaching agent is disposed in the pressure vessel, and wherein the leaching agent removes the catalyzing material from the interstitial spaces interposed between the diamond particles of the at least one polycrystalline diamond body, and wherein the at least one retention mechanism of the pressure vessel seals at least a portion of the carbide substrate into the at least one receiving mechanism and prevents the leaching agent from contacting at least a portion of the carbide substrate.
