Ti-Nb alloys with various Nb contents were fabricated by spark plasma sintering to investigate the effect of Nb on microstructure and corrosion behavior. Increasing Nb content promoted phase evolution toward β-phase dominance and significantly improved corrosion resistance, as confirmed by electrochemical measurements.
