摘要
An exemplary method of processing a polycrystalline diamond element includes positioning the polycrystalline diamond element within a protective leaching cup. The protective leaching cup includes a seal region contacting a portion of a side surface of the polycrystalline diamond element adjacent a cutting face of the polycrystalline diamond element. The protective leaching cup also includes an encapsulating region surrounding a rear face and a portion of the side surface of the polycrystalline diamond element adjacent the rear face. The method includes exposing at least a portion of the polycrystalline diamond element to a leaching agent. A length of a side wall of the protective leaching cup exceeds a length of the side surface of the polycrystalline diamond element.
