In this study, high-temperature oxidation behavior and electrochemical corrosion properties of Ti-25Nb-5Ta-2V (TNTV) and Ti-25Nb-5Ta-2Ni (TNTN) alloys performed. Thermogravimetric analyses indicated that both alloys exhibit mass gain with increasing temperature, attributable to the formation of oxide layers. The TNTV alloy demonstrated a more pronounced oxidation rate, which is ascribed to the elevated oxidative reactivity of vanadium. Electrochemical evaluations, including potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), revealed that TNTN possesses superior corrosion resistance in a simulated seawater, as evidenced by higher polarization resistance and charge transfer resistance relative to TNTV. These results highlight the significant influence of alloying elements on oxidation kinetics and corrosion mechanisms, indicating enhanced electrochemical stability of TNTN relative to TNTV.
