TiNbSn alloys have been used in biomedical applications for more than decades due to their excellent corrosion resistance, biocompatibility, and high mechanical strength with low Young’s Modulus. Although these alloys are in use for a long time, not many studies have been done using Additive manufacturing to check the material properties to fit certain bio-medical applications. In light of this, an attempt was made to deposit TiNbSn with variable quantities of Nb using laser-based directed energy deposition. The mass percentages of Nb in TiNbSn were varied from 30 wt.% to 35 wt.% and the additively manufactured samples were characterized for microstructures and phases. Biocorrosion response in terms of potentiodynamic polarization and electrochemical impedance spectroscopy of these samples were evaluated in simulated body fluid at physiological temperature (37 ℃) and were compared to that of the cast alloys. Moreover, these results were further related to the microstructural aspects evolved in the additively manufactured TiNbSn.
