A method of processing a polycrystalline diamond element includes forming a protective layer over a selected portion of a polycrystalline diamond element, the polycrystalline diamond element having a polycrystalline diamond table that includes a superabrasive face, a superabrasive side surface, and a chamfer extending between the superabrasive face and the superabrasive side surface. A portion of the superabrasive side surface is covered by the protective layer and the protective layer is not formed over the chamfer. The method includes exposing at least a portion of the polycrystalline diamond element to a leaching solution. A polycrystalline diamond element has a polycrystalline diamond table that includes a leached volume extending from the superabrasive face to a portion of the chamfer proximate to the superabrasive side surface, and the leached volume does not substantially extend along the superabrasive side surface.

Superabrasive elements and methods for processing and manufacturing the same using protective layers

Embodiments of the invention relate to polycrystalline diamond compacts ('PDCs') and methods of fabricating polycrystalline diamond tables and PDCs in a manner that facilitates removal of metal-solvent catalyst used in the manufacture of polycrystalline diamond tables of such PDCs.

Polycrystalline diamond compacts and related methods

In an embodiment, a polycrystalline diamond compacts ('PDC') includes a substrate and a polycrystalline diamond ('PCD') table bonded to the substrate. The PCD table defines an upper surface and at least one peripheral surface. The PCD table includes a plurality of bonded diamond grains. The PCD table includes a first region adjacent to the substrate that includes a metallic constituent disposed interstitially between the bonded diamond grains thereof, and a leached second region extending inwardly from the upper surface and the at least one peripheral surface that is depleted of the metallic constituent. The leached second region exhibits a leach depth profile having a maximum leach depth that is measured from the upper surface. A leach depth of the leach depth profile decreases with lateral distance from a central axis of the PCD table and toward the at least one peripheral surface.

Road-removal system employing polycrystalline diamond compacts

An exemplary method of processing a polycrystalline diamond element is disclosed. According to the method, a protective layer may be formed over only a selected portion of a polycrystalline diamond element. The polycrystalline diamond element may include a polycrystalline diamond table. At least a portion of the polycrystalline diamond element may be exposed 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 layer. The protective layer may be substantially impermeable to the leaching solution. An exemplary method of manufacturing a polycrystalline diamond element is also disclosed.
