摘要： An abrasive compact having at least a tri-modal particle size distribution, and a binder phase, define a plurality of interstices. The binder phase is distributed in the interstices to form binder pools that correspond substantially in average size to that of an ultrahard polycrystalline composite material having a monomodal particle size distribution and substantially the same overall average particle grain size.

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 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 cutting element consists generally of a layer of high grade polycrystalline diamond bonded to a cemented carbide substrate. The polycrystalline diamond layer has a working surface and an outer peripheral surface and is characterized by having an annular region or a portion thereof adjacent the peripheral surface that is lean in catalysing material. A region adjacent the working surface is also lean in catalysing material such that in use, as a wear scar develops, both the leading edge and the trailing edge thereof are located in a region lean 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 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.
