Abstract:
1. A system for producing thermally stable cutting elements, comprising: a heat source; a pressure vessel capable of operating under a pressure of 1.2 to 345 bar, comprising: a container comprising at least one receiving mechanism and at least one retention mechanism; at least one polycrystalline diamond body attached to a carbide substrate, wherein the carbide substrate is disposed in the at least one receiving mechanism of the pressure vessel, and wherein the polycrystalline diamond body comprises interconnected diamond particles with a catalyzing material to be removed from the interstitial spaces interposed between the diamond particles; a leaching agent, 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.
