    摘要： A cubic boron nitride compact is bonded to a cemented carbide support through an alloy bonding layer which contains 40 to 70 percent by weight silver, gold or a combination thereof and 1 to 10 percent by weight of a high melting metal selected from the group of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium and molybdenum. Bonding may be achieved by first metallizing a surface of the cubic boron nitride compact with a layer of gold or silver or a gold or silver based alloy and then bonding the metallized layer to the carbide support by means of a braze alloy having a liquidus temperature above 700.degree. C.

    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-oxidizing atmosphere and being chosen to allow chemical bond formation between the particles and the coating.

    摘要： An abrasive body is provided which has high strength and an ability to withstand high temperatures making it suitable as a tool insert for dressing tools and surface set drill bits. The body comprises a mass of diamond particles present in an amount of 80 to 90 percent by volume of the body and a second phase present in an amount of 10 to 20 percent by volume of the body, the mass of diamond particles containing substantial diamond-to-diamond bonding to form a coherent skeletal mass and the second phase containing nickel and silicon, the nickel being in the form of nickel and/or nickel silicide and the silicon being in the form of silicon, silicon carbide and/or nickel silicide. The abrasive bodies are made under conditions of elevated temperature and pressure suitable for diamond compact manufacture.
