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 tool component comprises an abrasive compact layer bonded to a cemented carbide substrate along an interface. The abrasive compact layer has a working surface, on a side opposite to the interface. This working surface is flat and presents a cutting edge or point around its periphery. A recess extends into the substrate from the interface. The recess has a side wall and a base both of which are located entirely within the carbide substrate. The recess has a portion located in the interface. The area of this portion is at least 25 percent the area of the interface. A material, different to that of the substrate, fills the recess and is bonded to the substrate. This material will typically be abrasive compact of the same type as the abrasive compact layer, or a cemented carbide which has characteristics different to that of the substrate.

摘要： The invention concerns a diamond bearing assembly for a downhole motor. The assembly (10) includes at least one set of opposing, relatively rotating thrust bearing rings (20, 22) each of which includes an annular support element (24, 30) and PCD compacts (26, 32) carried by the support elements. The PCD compacts of the bearing rings oppose one another at a thrust bearing interface (80). Shear limiting means (96, 110) are provided. These means are arranged to shear if frictional forces between the opposing PCD compacts at the thrust bearing interface exceed a critical level. This eliminates relative rotation between the bearing rings and avoids possible overheating and thermal degradation of the PCD. The shear limiting means can also serve as an alignment means to ensure correct axial alignment of the bearing components. The bearing assembly may also include a compact radial bearing capability.
摘要翻译：本发明涉及一种用于井下电动机的金刚石轴承组件。组件（10）包括至少一组相对的，相对旋转的推力轴承环（20,22），每个轴承环包括由支撑元件承载的环形支撑元件（24,30）和PCD压块（26,32）。轴承圈的PCD压块在推力轴承接口（80）处彼此相对。提供剪切限制装置（96,110）。如果在推力承载接口处的相对的PCD压块之间的摩擦力超过临界水平，则这些装置被布置成剪切。这消除了轴承环之间的相对旋转，并避免了PCD的过热和热降解。剪切限制装置还可以用作对准装置以确保轴承部件的正确轴向对准。轴承组件还可以包括紧凑的径向承载能力。

摘要： Thermally stable abrasive compacts of hexagonal shape have been found to have excellent abrasive properties in the abrading of a medium to soft rock having an unconfined compressive strength of less than 240 MPa. Preferably the abrasive tool used is a surface set drill bit wherein some of the thermally stable abrasive compacts are so located around the working edge of the bit that a side thereof acts as a gauge stone for the working portion.
