摘要： A method of producing a tool component comprising a working portion of bonded abrasive particles including a non-homogeneous region. The method includes the step of providing at least two sources of a material comprising abrasive particles in a suitable binder, the materials of the sources differing from each other. The material of one source may comprise diamond or cubic boron nitride particles, whilst the material of the other source may comprise carbide particles. Alternatively, the materials of the two sources may contain the same abrasive particle, such as diamond or cubic boron nitride particles, but in different particle sizes. The materials are delivered to a zone where mixing occurs, and the mixture is applied to a surface to produce a layer of the mixed materials on the surface, typically by spraying. By controlling the quantity of material from each source which is delivered to the mixing zone, different mixtures of the two abrasives can be created. In this way, layers, e.g. one on top of the other, can be produced which differ from their neighbours in abrasive particle composition. These layers, on sintering, form non-homogeneous regions in the working portion of a tool component.

摘要： A method of producing an abrasive product comprises providing a mixture of a mass of discrete carbide particles and a mass of diamond particles, the diamond particles being present in the mixture in an amount such that the diamond content of the abrasive product is 25 % or less by weight, and subjecting the mixture to elevated temperature and pressure conditions at which the diamond is crystallographically stable and at which substantially no graphite is formed, in the presence of a bonding metal or alloy capable of bonding the mixture into a coherent, sintered product, to produce the abrasive product. The bonding metal or alloy is preferably a combination ofa transition metal or a transition metal alloy and up to 40% by volume of the bonding metal or alloy of a second metal which is a stronger carbide former than the transition metal or the transition metal alloy, or an alloy of the second metal.

摘要： An abrasive and wear resistant material comprises a mass of carbide particles, a mass of cubic boron nitride particles, and a bonding metal or alloy, bonded into a coherent, sintered form. The cubic boron nitride particle content of the material is from 10% to 18% inclusive by weight, the particle size of the cubic boron nitride is less than 20 micron or less, and the material is substantially free of hexagonal boron nitride. The abrasive material is of particular use in tool components or inserts for application in the abrading of wood and other lignocellulosic materials.
