Abstract

Ti(C_0.5N_0.5)-(Ni-Co)-Mo₂C-Cr₃C₂ system cermet with low content of Mo₂C was fabricated by hot pressure technology. The mechanical properties and SEM microphotography of the fracture surface and indention crack propagating on ground surface of the Ti(C,N) based cermet with different contents of Cr₃C₂ were discussed. It is shown that the flexure strength increases with the increase of Cr₃C₂ content and the fracture toughness of the cermet slightly decreases with the content of Cr₃C₂ when Cr₃C₂ content is less than 8%(mass fraction) and deeply decreases when Cr₃C₂ content more than 8%.

Key words
