Problems solved by technology

[0004] Although PCBN inserts have excellent hardness, wear resistance, thermal stability, thermal conductivity, Young's modulus, and thermal expansion, the fracture toughness of PCBN inserts is poor, which is less than half of that of ceramic inserts, which limits the development of PCBN inserts.

Abstract

The invention discloses a whole PCBN blade binder and a preparation method thereof. The preparation method comprises the steps that (1) cobalt powder, nickel powder, silica powder and palladium powderare subjected to heat treatment under the presence of protective gas, then cooled, and subjected to first-time ball grinding to obtain a ball-ground object; (2) the ball-ground object, alumina, titanium nitride and silicon carbide are subjected to second-time ball grinding to obtain a mixture; and (3) the mixture, potassium titanate whiskers and graphene are mixed to obtain the whole PCBN blade binder. The whole PCBN blade binder enables a prepared whole PCBN blade to have excellent fracture toughness, and meanwhile the preparation method has the advantages that the process is simple, and theraw materials are easy to obtain.
