POLYCRYSTALLINE DIAMOND ABRASIVE ELEMENTS |
摘要 |
<p>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 characterised 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.</p> |
