Abstract: Effects of addition of rare earth element Er on the bending strength and hardness of Ti(C,N) based cermets have been studied. The results have shown that the appropriate addition of rare earth element Er can increase the bending strength and hardness. This is mainly due to the reaction of element Er with impurity element S, which forms compound particles, hence, cleans the interfaces of ceramics /metals and ceramics/ceramics, and the metals, thus increasing the interfacial bonding strength.
