Ti-ZrO2 bilayered composite was synthesized by vacuum hot pressing sintering under 1 200 ℃ and 10 MPa through interfacial doping of graphene.The interfacial bonding was characterized by tensile strength.The interfacial phase compositions and element distributions were analyzed by X-ray diffraction（XRD）and scanning electron microscopy（SEM）,respectively.The results show that graphene could not exist stably on the interface,nor form titanium carbides.Instead,it dissolves into the lattices of titanium and zirconia,which hinders the mutual diffusion of titanium and zirconia,avoiding the formation of TiO2 and ZrTiO4.The interface is under the state of diffusion bonding with the strength reaching 52.1 MPa±3.8 MPa.
