摘要： A tool component comprising a wear part covered at least in part by a connection member, the wear part having a specified hardness and the connection member being a metal or alloy, and the wear part comprising a surface that includes one or more depressions or projections therefrom, and the connection member having been pressed against that surface so that at least the surface of the connection member that faces the wear part surface follows the profile of the wear part, whereby relative movement between the wear part and connection member is substantially prevented. The metal or alloy connection member may be readily attached to a tool body for example by brazing of the like. The wear part may comprise a material that is not readily brazeable, for example a ceramic material or a cermet or a superhard material or a composite of such materials.

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 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.
