    摘要： A tool insert comprising a composite diamond abrasive compact and a method of its production are provided. The composite abrasive compact is characterised by an intermediate layer (14) between the diamond compact (10) and the cemented carbide support (12). The intermediate layer (14) consists essentially of discrete cubic boron nitride particles constituting 60 to 40 percent by volume of the intermediate layer, carbide particles, preferably tungsten carbide particles and diamond solvent, preferably cobalt. The carbide particles and diamond solvent together constituted 40 to 60 percent by volume of the intermediate layer and the diamond solvent constitutes 15 to 25 percent by volume of the carbide/solvent combination.

    摘要： A tool insert comprises an abrasive compact comprising a polycrystalline mass of cubic boron nitride particles present in an amount of at least 70 percent by volume and containing substantial direct particle-to-particle bonding and a second phase dispersed through the cubic boron nitride particle mass. The abrasive compact presents major surfaces on each of opposite sides thereof. The one major surface provides a cutting point for the insert and the other major surface has bonded thereto a layer of molybdenum of thickness less than 0,5 mm. The largest linear dimension of the compact is no more than 10 mm. The tool insert is designed for applications where a high removal rate of work piece is desired.

    摘要： A composite abrasive compact is produced by placing strips (16),(18) of suitable abrasive material on a cemented carbide substrate (10). The strips each comprise abrasive particles, optionally with a particulate second phase, in an organic binder. The organic binder is first removed by volatilisation. Then, the cemented carbide substrate (10) with the strips (16),(18) thereon is subjected to compact-producing conditions of elevated temperature and pressure.
