Abstract: The microstructure of Ti-Mo-Zr alloy fabricated by selective laser melting (SLM) was studied and its corrosion behavior was investigated by a series of electrochemical methods. The results showed that α+β phases of different proportions were formed after heat treatment, the grain size of the alloy treated at 950℃ slightly increased, because of the existence of the original α grain, the orientation of the α grain was not significantly changed by heat treatment below the β transition temperature. However, heat treatment above β transition temperature significantly changed the orientation of α grains. Electrochemical measurements were conducted in artificial saliva solution and artificial saliva solution containing hydrogen peroxide . The results showed that the corrosion resistance of the original Ti-Mo-Zr alloy was better than that of the Ti-Mo-Zr alloy treated at 950°C and worse than that of the Ti-Mo-Zr alloy treated at 1050°C. The differences in corrosion behavior can be attributed to grain size and orientation and phase distribution.
