Abstract

Abstract

Mo₂C is normally added to improve the wettability between Ti(C,N) and Ni in Ti(C,N)-based cermets.Due to the increasing price of Mo₂ C,much attention has been paid to Ti(C,N)-based cermets with WC addition.In this paper,effect of WC content on the microstructure of Ti(C_0.7N_0.3)-xWC-15%Ni cermets free of Mo₂ C was studied.The experimental results show that all the WC had been solid solved with TiC_0.7N_0.3or dissolved into Ni binder phase, and all the cermets have core-rim structure.WC has a strong effect of grain re-finement on microstructure(average grain size is below 10 μm) when WC content is above 20%.
