  • Sintered compact
    Patent number: 8500834
    Abstract: A sintered cubic boron nitride (cBN) compact for use in a tool is obtained by sintering a mixture of (i) cubic boron nitride, (ii) aluminum oxide, (iii) one or more refractory metal compounds, and (iv) aluminum and/or one or more non-oxide aluminum compounds. The sintered bodies may have sufficient strength and toughness to be used as a tool material in solid, i.e. not carbide supported, form, and may be useful in heavy machining of cast irons.
    Type: Grant
    Filed: August 2, 2010
    Date of Patent: August 6, 2013
    Assignee: Diamond Innovations, Inc.
    Inventors: Stephen Dole, Dwight Dyer, Rajeev Pakalapati, James McHale
  • METHOD OF SOLID PCBN SYTHESIS
    Publication number: 20130061534
    Abstract: The invention generally relates to a sintered CBN composite compact having a non-CBN portion. The compact includes about 86 to about 90% CBN and the non CBN portion contains borides and nitrides of Al. The compact is for use as a cutting tool insert in continuous machining of gray cast iron. The sintered compact has a thermal conductivity of 1.25-4 W/cm/° K. in the temperature range of about 200° C. to about 600° C. and sonic velocity of at least about 14.5 Km/sec at room temperature.
