Abstract: A method of processing a polycrystalline diamond element is disclosed. The method may include depositing a vaporized material over a selected portion of a polycrystalline diamond element to form a protective coating over the selected portion. The polycrystalline diamond element may include a polycrystalline diamond table. The method may also include exposing at least a portion of the polycrystalline diamond element to a leaching solution such that the leaching solution contacts an exposed surface region of the polycrystalline diamond table and at least a portion of the protective coating. The method may also include removing the polycrystalline diamond element from the leaching solution. The protective coating may be substantially impermeable to the leaching solution.

Abstract: The disclosure provides a super abrasive element containing a substantially catalyst-free thermally stable polycrystalline diamond (TSP) body having pores and a contact surface, a base adjacent the contact surface of the TSP body; and an infiltrant material infiltrated in the base and in the pores of the TSP body at the contact surface. The disclosure additionally provides earth-boring drill bits and other devices containing such super abrasive elements. The disclosure further provides methods and mold assemblies for forming such super abrasive elements via infiltration and hot press methods.
