发明名称 Supported thermally stable cubic boron nitride tool blanks and method for making the same
摘要 A method for making supported, thermally stable cubic boron nitride (CBN) or wurtzitic boron nitride (WBN) compacts or wire dies comprising providing a mass of sinterable CBN and WBN particles substantially free of catalytic material and a metal bonded support mass or annulus; positioning a barrier layer between said CBN or WBN mass and said support mass; and subjecting such arrangement of materials to pressure and temperature conditions for a time effective for sintering said CBN or WBN particles and substantially preventing migration of metal bond material into the CBN or WBN mass.
