| Abstract: | The standard Gibbs free energy of Ti2O was predicted according to the quasi-parabola rule. The co-existing region of Ti and ZrO2 was obtained by thermodynamic calculation to determine the synthesis conditions of this composite. ZrO2-Ti system composites sintered under ordinary pressure were prepared by a powder metallurgical method. The gradient distribution of composition, the interfacial microstructure between layers and the combining state of phases between Ti and ZrO2 were investigated by means of XRD, SEM, EDS, TEM and so on. The experimental results show that the joint between Ti and ZrO2 phases is physical in this composite. ZrO2 mainly exists as a tetragonal phase. |
