Effect of Ru on Microstructure and Properties of Ti(C,N)-based Cermets AITranslate
Abstract AITranslate
Ti(C5N5),Mo2C,Ru and Ni powders were mixed,and then Ti(C,N)-based cermets were prepared by powder metallurgy.The effects of Ru on microstructure and properties of Ti(C,N)-based cermets were studied as well as the mechanism.The results show that the Ti(C,N)-based cermets doped with Ru exhibit a core-ring structure.With the increase of Ru content,the main grains are refined,and the binder phase tends to be uniform.The change in Ru content has an effect on the concentration gradient of the binder phase in Ti(C,N)-based cermets.The thickness of the gradient layer increases at first and then decreases as the Ru content increases.Ti(C,N)-based cermet with 1.5% Ru has fracture toughness of 9.9 MPa·m1/2 and Vickers hardness of 1 500 HV10.Ru doping greatly improves the comprehensive mechanical properties of Ti(C,N)-based cermets,due to strengthening of the binder phase.
