A method of processing a polycrystalline diamond element may include providing a protective leaching cup having a rear wall, an opening defined by a portion of the protective leaching cup opposite the rear wall, and a side wall extending between the opening and the rear wall, the side wall and the rear wall defining a cavity within the protective leaching cup. The method may further include positioning a polycrystalline diamond element in the cavity defined within the protective leaching cup. Positioning the polycrystalline diamond element in the cavity may include expanding at least a portion of the opening outward from a center of the opening. The method may additionally include exposing at least a portion of the polycrystalline diamond element to a leaching agent.

A novel diamond cutting tool and its use in cutting and grinding applications. The cutting surface of the tool is composed of an aluminum/diamond metal matrix composite comprising diamond particles dispersed in a matrix of aluminum or an aluminum alloy, and wherein the diamond particles have thin layers of beta-SiC chemically bonded to the surfaces thereof.

A cemented carbide body includes WC in a metallic binder phase. The cemented carbide body has a bulk portion and a surface portion. The grain size of the WC in the surface portion is smaller than the grain size in the bulk portion of the body and this gives an increased surface hardness and an increased wear resistance. The median grain thickness, tg, of WC in the surface portion is 20-300 nm and the average grain size in the bulk portion is 0.5-8 μm. A method of surface hardening a cemented carbide body is also provided.

A composite machining tool includes a tool body with at least one cutting edge and at least one grinding region. The grinding region is located adjacent to the cutting edge such that there is a gap between the grinding region and the cutting edge and such that when the tool performs a machining action the cutting edge and the grinding region act together on a material surface.

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.

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Polycrystalline diamond constructions comprise a diamond body attached with a substrate during high pressure/high temperature processing, and include a modified reaction zone interposed between the body and substrate that is engineered to minimize or eliminate unwanted back diffusion of carbon from the diamond body into the substrate during the high pressure/high temperature processing.

A cleaning system and a method for cleaning a surface of a ferromagnetic object are disclosed. Accordingly, to an example configuration, the cleaning system includes a device body that comprises a magnetic system that urges an abrasive layer against the surface of the ferromagnetic object by a magnetic force. In at least some examples, the magnetic force provided by the magnetic system is adjustable to achieve a target magnetic force for cleaning the surface.
