摘要： A polycrystalline diamond abrasive element, particularly a cutting element, comprises a table of polycrystalline diamond bonded to a substrate, particularly a cemented carbide substrate, along a non-planar interface. The non-planar interface typically has a cruciform configuration. The polycrystalline diamond has a high wear-resistance, and has a region adjacent the working surface lean in catalysing material and a region rich in catalysing material. The region lean in catalysing material extends to a depth of 40 to 90 microns, which is much shallower than in the prior art. Notwithstanding the shallow region lean in catalysing material, the polycrystalline diamond cutters have a wear resistance, impact strength and cutter life comparable to that of prior art cutters, but requiring only 20% of the treatment times of the prior art cutters.

摘要： A composite part comprises (a) a cutting element which comprises super-hard cutting table and a substrate and (b) a metal or alloy layer. Respective first surfaces of the superhard cutting table and the substrate are joined to each other, and the metal or alloy layer is located adjacent to second surfaces of the cutting table and the substrate so as to surround the joined first surfaces of the cutting table and the substrate. The metal or alloy layer and the second surfaces of one or both of the cutting table and substrate are co-operatively shaped substantially to prevent relative movement therebetween. The metal or alloy layer may be used to secure the cutting element within a tool body, and advantageously provides a convenient means to effect that securement, while simultaneously protecting the join between the superhard cutting table and the substrate during the process of securement of the cutting element to the tool body.

摘要： A rotary drag bit comprises a bit body and a plurality of blades extending radially away from the bit body, each blade including a cutting assembly. Each cutting assembly has a plurality of primary cutters orientated in the direction of rotation of the drill bit for drilling or boring into a subterranean rock formation, and a plurality of secondary or brute cutters located behind the primary cutters in relation to the direction of rotation of the drag bit. The invention is concerned primarily with the secondary cutters, which comprise a layer of superabrasive material, such as PCD, PCBN or CVD diamond, bonded to a support substrate. The interface between the superabrasive layer and the substrate has a stepped region that provides the cutter with a skirt or hoop of superabrasive extending into the substrate. The secondary cutter is orientated in use to present a bearing surface to the rock formation and a secondary cutting edge in the direction of rotation of the rotary bit.
