摘要： A method of producing diamond crystal growth on a seed crystal is provided. The method includes the steps of providing a seed crystal containing at least one twin plane and re-entrant growth surfaces associated therewith and applying high temperature/high pressure synthesis conditions to the seed crystal to cause diamond growth to occur preferentially on the re-entrant surfaces. The diamond growth on the seed crystal results in a diamond crystal being produced which has an aspect ratio greater than 1.

摘要： A cubic boron nitride cluster comprises a core (10) and an overgrown region, the overgrown region containing a plurality of cubic boron nitride crystallites (12) extending outwards from the core (10). The majority of the cubic boron nitride crystallites (12) have a cross-sectional area which increases as the distance from the core (10) increases. A method of producing cubic boron nitride clusters is also provided.

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 polycrystalline diamond abrasive element is characterized by the nonplanar interface having a cruciform configuration, the polycrystalline diamond having a high wear-resistance, and the polycrystalline diamond having a region adjacent the working surface lean in catalysing material and a region rich in catalysing material. The polycrystalline diamond cutters have improved wear resistance, impact strength and cutter life than prior art cutters.

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 characterized 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 catalyzing material and a region rich in catalyzing 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 crucifonn configuration. The polycrystalline diamond has a high wear-resistance, and has a region adjacent the working surface leanin 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.
