摘要： A polycrystalline diamond abrasive element, particularly a cutting element, comprises a layer of polycrystalline diamond having a working surface and bonded to a substrate, particularly a cemented carbide substrate, along an interface. The polycrystalline diamond abrasive element is characterised by using a binder phase that is homogeneously distributed through the polycrystalline diamond layer and that is of a fine scale. The polycrystalline diamond also has a region adjacent the working surface lean in catalysing material and a region rich in catalysing material.

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： In a method of producing a tool component a plurality of fibres is formed into a bundle. Each fibre has a core comprising a mass of ultra-hard abrasive particles or precursor to said ultra-hard abrasive particles and optionally a second phase, and a coating comprising a mixture of carbide particles and particulate binder metal. After extruding the bundle of fibres, the bundle is severed transverse to its length to produce a layer 24. The layer 24 is placed on a surface 26 of a substrate 28 and the layer 24 and substrate 28 are subjected to elevated temperature and pressure conditions at which the ultra-hard abrasive particles are crystallographically stable. The composition of the core and coating may be interchanged in the method.

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.

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 tool insert comprises a substrate (10) having a support surface and a support ring extending laterally from the support surface. The support ring is sized to define a recess (14) within the confines thereof and a shelf about the periphery thereof. A layer (12) of ultra-hard abrasive material is located within the recess and bonded to the substrate and the support ring (16), and presents a primary cutting edge (22) for the tool insert. A protective layer (18) is bonded to the shelf about the support ring so as to protect the primary cutting edge. The protective layer provides a secondary cutting edge (20) for the tool insert, the depth of the protective layer being selected so as to be sufficient to protect the primary cutting edge whilst cutting, milling or drilling through a first substance but to expose the primary cutting edge upon encountering a second substance.
