Abstract

The invention discloses a wear-resistant carbide-based metal ceramic knife and a manufacturing method thereof. The wear-resistant carbide-based metal ceramic knife is manufactured by, by weight, 40-50 parts of titanium carbide, 45-60 parts of silicon carbide, 20-30 parts of copper powder, 3-11 parts of asbestos powder, 3-6 parts of maldonite powder, 1-5 parts of diaspore powder, 3-8 parts of graphene, 3-6 parts of potassium oxide, 10-15 parts of glass fiber and 11-15 parts of paraffin. Compared with conventional metal ceramic knives, the wear-resistant carbide-based metal ceramic knife manufactured by the method has higher wear resistance and heat resistance and excellent cutting performance; through optimization of components and content, compactness and bending resistance of metal ceramic tissue are improved remarkably, and the wear-resistant carbide-based metal ceramic knife can be widely used for high-speed cutting of low-medium-carbon steel and low-alloy steel.

Description

technical field [0001] The invention specifically relates to a wear-resistant carbide-based cermet cutter and a preparation method thereof. Background technique [0002] Cermet English word cermet or ceramet is composed of ceramic (ceramic) and metal (metal). Cermet refers to the composite material of metal and ceramic prepared by powder metallurgy method. Cermet has the advantages of both metal and ceramic. It has low density, high hardness, wear resistance and good thermal conductivity. Brittle. Cermet not only has the toughness, high thermal conductivity and good thermal stability of metal, but also has the characteristics of high temperature resistance, corrosion resistance and wear resistance of ceramics. Cermets have broad application prospects in aerospace, national defense, precision manufacturing and other fields. Carbide-based cermets are based on titanium carbide, silicon carbide, tungsten carbide, etc., and are compounded with metals such as cobalt, nickel, ch...
