  • Abrasive product
    Patent number: 4378975
    Abstract: The invention provides an abrasive body which will generally be of cylindrical shape comprising a plurality of superhard abrasive particles such as diamond bonded together by means of a tough wear-resistant nickel based alloy having a melting point of below 1000.degree. C. These alloys are known as hard facing alloys. The abrasive bodies may be used as inserts for drill crowns. The bodies are made by mixing the abrasive particles with the alloy in powdered form, producing a green-state, coherent body from the mixture, generally by cold pressing, and sintering the green-state product under conditions which inhibit degradation of the abrasive particle.
