Abstract

The invention discloses a metal ceramic material, and belongs to the technical field of metal ceramic materials. The metal ceramic material comprises, by weight, 60-80 parts of a principal phase, 16-20 parts of a binding phase, 5-10 parts of carbide, 3-10 parts of an additive, 5-10 parts of whiskers and 5-10 parts of auxiliaries. SiC and/or TiC serve/serves as the whiskers, and carbon nano tubes serve as the auxiliaries. Through adding of the whiskers Sic and/or TiC and the auxiliary carbon nano tubes, the strength of the metal ceramic material is high, toughness is enhanced, and the application range of a metal ceramic cutter manufactured through a powder metallurgy manner is wide.

Description

technical field [0001] The invention relates to the field of cermet materials, in particular to a cermet material. Background technique [0002] Cermet is a composite material, which is a structural material composed of a ceramic hard phase and a metal or alloy binder phase. Cermet not only maintains the high strength, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability of ceramics, but also has good metal toughness and plasticity. [0003] According to the different percentages of each constituent phase, cermets are divided into two types: ceramic-based and metal-based. Ceramic-based cermets mainly include: oxide-based cermets, carbide-based cermets, nitride-based cermets, boride-based cermets, and silicide-based cermets; It is made of powder, also known as dispersion reinforced material. [0004] Cermet has the advantages of both metal and ceramics. It has low density, high hardness, wear resistance, good thermal cond...
