Abstract
PURPOSE: To manufacture a cubic system boron nitride bound body as a super hard tool material by sintering cubic system boron nitride powder as a hard material together with aluminum tertiary phosphate powder and specified metal powder as a binder.
CONSTITUTION: 60W96wt% Cubic system boron nitride powder is mixed with 20W 2wt% aluminum tertiary phosphate powder and 20W2wt% powder of one or more among A, Fe, Si, Cu, Ti, Zr, Cr, Mn, Co and Ni or an alloy of two or more among them as a binder. A container is filled with this mixed starting material, placed in a high temp. and high pressure generator, and slowly heated to 1,000W1,400°C under 39,000W60,000kg/cm2 sintering pressure. After sustaining this state for severalWseveral tens min the material is further heated to a sintering temp. up to 1,600°C and sintered to manufacture a super hard tool material contg. cubic system boron nitride as the hard material.
