Effect of Alloying Elements Zr, Cr, V on Corrosion Behavior of Ti-Ni-Nb Shape Memory Alloy

By testing anodic polarization curves of Ti-Ni-Nb-based shape memory alloys, the stability of passive film was investigated after alloying with the elements Zr, Cr, and V. In artificial sea water (3.5 pct NaCl) and physiological solution (5 pct NaCl + 0.1 pct H2O2), the results show that the alloyin...

Zusammenfassung:By testing anodic polarization curves of Ti-Ni-Nb-based shape memory alloys, the stability of passive film was investigated after alloying with the elements Zr, Cr, and V. In artificial sea water (3.5 pct NaCl) and physiological solution (5 pct NaCl + 0.1 pct H2O2), the results show that the alloying elements influence the corrosion behavior of Ti-Ni-Nb alloy. Generally, Zr improves the corrosion resistance of Ti-Ni-Nb alloy, Cr reduces its corrosion resistance, and V does not change its properties. (Author)
