Analyzing the microstructure of the reaction interface was characterized with XRD and SEM/EDS after reaction. α-Ti(Al、V、O) and TixOy are found in Ti-6Al-4V side after diffusion reaction for all samples. In ceramic side, each sample have found different phases because each phase have diverse affinity with Ti. Some of the compound have been observed, including Y2O3,α-Ti(Al、V、O), Y-ZrO2, Y4Al2O9, Ti3Al, AlZr2, Al3Zr2, YAlO3, etc.The affinity with Ti of those compound can be fall into rank as Al2O3 > YAG > Y-ZrO2> Y2O3. YAG has play an important role during diffusion process. It will be necessary to analysis YAG and Ti-6Al-4V diffusion reaction with the same temperature and time.
