Abstract
PURPOSE: To produce a cubic boron nitride consolidated body having superior performance as a hard tool material by mixing cubic boron nitride powder, stabilized zirconia powder, Al powder or further Al2O3 or TiN powder and sintering the mixture in 2 stages.
CONSTITUTION: Raw mateials are mixed n threeways of compounding ratios of 50W80% powdery cubic boron nitride powder, 43W10% stabilized zirconia powder, 7W10% A powder or 23W6% stabilized zirconia powder and the balance 20W4% Al2O3 powder or 20W5% stabilized zirconia powder and the balance 23W5% TiN powder. The compounded raw materials are put in a vessel, which is put in a high temp. high pressure generating chamber where they are presintered at 1,000W1,400°C and 33,000W43,000kg/cm2 pressures, after which they are subjected to regular sintering at 1,400W1,600°C and 43,000kgW53,000kg/cm2. The hard tool material as a cubic boron nitride consolidated body provided with superior cutting characteristics is obtained.
