Abstract
PURPOSE: To manufacture a solidified body of cubic system BN used as a material for a superhard tool by mixing powder of cubic system BN with mixed metallic powder consisting of powder of a specified metal and Mg powder in a specified ratio and by pressurizing and heating the mixture under specified conditions.
CONSTITUTION: 70W95wt% Powder of cubic system BN is mixed with 30W5wt% mixed metallic powder prepared by adding Mg powder to powder of 1 or ≥2 kinds of metals selected from Ni, Co, Fe, Cr, Mn, Si and Al. This mixture is preliminarily sintered by heating to 1,000W1,400°C after pressurization to 32,000W 45,000kg/cm2 in a chamber providing high temp. and pressure. The pressure is then raised to 43,000W55,000kg/cm2, and the preliminarily sintered body is heated to 1,400W1,600°C. Thus, a spongy metallic structure made of Mg alloy as a binder region combines with each of particles of cubic system BN in an aggregate composed of many particles of cubic system BN.
