| Abstract: | The effects of rare earth element Y on the mechanical properties and microstructure of Ti(C,N) based cermets have been studied in this paper. The experimental results have shown that the appropriate addition of rare earth element yttrium can increase the bending strength and hardness, and the reason is mainly due to the reaction of element yttrium with impurity element sulphur, resulting in forming compound particles, as well as cleaning the interfaces of ceramics ceramics and ceramics metals. Therefore the interfacial bonding strength is increased. |
