摘要： The invention provides a method of metal coating diamond or cubic boron nitride particles, the metal being capable of forming a chemical bond with the particles, including the steps of providing a mass of metal for the coating in powdered form in contact with the particles, heat treating the metal powder and the particles at a temperature below the melting point of the metal to deposit a layer of metal on the particles, and recovering the particles as discrete, metal coated particles, the heat treatment taking place in a non-oxidising atmosphere and being chosen to allow chemical bond formation between the particles and the coating.

摘要： The invention provides a method of shaping a surface of a diamond compact (10), particularly one mounted on a cemented carbide backing (12), by means of a tool, particularly a wheel, in which the working surface is a carbide- forming metal or an alloy containing a carbideforming metal. The preferred working surface is mild steel.

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

摘要： A layer of single crystal CVD diamond of high quality having a thickness greater than 2 mm. Also provided is a method of producing such a CVD diamond layer. The method involves the homoepitaxial growth of the diamond layer on a low defect density substrate in an atmosphere containing less than 300ppb nitrogen. Gemstones can be manufactured from the layer.
