| Abstract: | Nanoparticle-modified cermets are attracting extensive attentions for their excellent mechanical properties.The experimental preparation,microstructure and mechanical properties of the nanoparticle-modified cermets are introduced,and the formation of core/rim structure in the cermets is dicussed.The results show that the crystal grains get finer with the increase of Mo2C content.The cermet has the highest hardness value when the content of Mo2C reaches 10%. |
