Electrochemical corrosion of Ti-35Nb-5Ta-7Zr alloy fabricated by arc melting and heat treatment process was studied in 0.9% NaCl at(37±1) ℃.Phase and microstructure of the fabricated alloy were investigated using X-ray diffractometer and scanning electron microscope.Mechanical properties such as yield strength and elastic modulus of the alloy were determined by tensile test.Potentiodynamic polarization technique and impedance spectroscopy were employed to study the corrosion behavior.The results of the study were compared with those obtained for Ti-6Al-4V commercial alloy.The result of the study supports feasibility of Ti-35Nb-5Ta-7Zr alloy for implant applications.
