Abstract

Provided are Ti(C,N)-based cermets with NiAl and Ni as binder and a preparation method thereof. The Ti(C,N)-based cermets are prepared by raw materials subjected to ball-mill mixing, die forming, vacuum degreasing and vacuum sintering, wherein weight percentage of each chemical component of the raw materials is as follows: TiC 34.2˜43%, TiN 8˜15%, Mo 10˜15%, WC 5˜10%, graphite 0.8˜1.0%, Ni 20˜24%, and NiAl powder containing B 6˜10%. Ni powder and NiAl powder containing B are used as binder. The Ti(C,N)-based cermets feature in excellent corrosion resistance, oxidation resistance and mechanical properties at high temperature, has a hardness of 89.0˜91.9 HRA, a room temperature bending strength of 1600 MPa or more, and a fracture toughness of 14 MPa·mor more, and is applicable for manufacturing high-speed cutting tools, dies and heat-resisting and corrosion-resisting components.
