Cutter blade made of ceramics formed of plural layers of super hard material group and oxide group

Abstract

Abstract PURPOSE:To improve abrasiveness by brazing two layers of super hard material whose base is oxide and of oxide and ceramics adhered with Cu material to the base metal of a cutter. CONSTITUTION:A Cu layer formed by adhering ceramics layer of oxide group of ceramics which are sintered so as to form two layers of super hard material group which becomes cutting edge by dispersing carbide, boride and nitride such as TiC, TiB2, Si3N4 and reinforcing with oxide such as Al2O3, ZrO2, MgO etc. as base and of oxide group which becomes adhesion medium of the same kind of the said oxide as the base to Cu or Cu alloy by oxidation reaction is adhered to the base metal of the cutter by brazing. Then, super hard material ceramics can firmly be adhered the oxide layer as an adhesion medium with the metal, and a long life cutter made of nonmetal hard material for which super abrasiveness is required can be obtained.
