Abstract
A method of producing a composite compact of cBN and WC-Co, comprising: mixing fine particles of cBN with a minor part of titanium carbide, the former being in an amount of 60-80% and the latter 40-20%, correspondingly, of the combined volume, putting the mixture in an intimate contact with a composite of WC-Co, heating the whole to a temperature high enough to cause an outflow of a liquid phase from said composite and infiltration thereof into said mixture under a pressure-temperature condition where cubic boron nitride is crystallographically stable, interjoining adjacent particles of cBN and titanium carbide, and as a whole to the composite of WC-Co, and recovering the integrated product of cBN, titanium carbide and WC-Co.
