The goals of this study were to assess the influence of temperature and pH on the corrosion resistance of Nitinol. Electropolished NiTi and passivated 316L stainless steel wires were tested in Hank’s physiological solution at temperatures ranging from 10°C to 80°C and pH varying from 1 to 9. Results show that the ability of Nitinol to repassivate is reduced by an increase in temperature. No other major effects were observed by a change in temperature. Stainless steel corrosion rate, on the other hand, was the only parameter affected by an increase in temperature. Study of the effect of pH revealed that except for a change in the potential for oxygen evolution, other aspects of the corrosion resistance of NiTi were not affected. In contrast, the results for stainless steel indicate that both uniform corrosion rate and localized corrosion are affected by a decrease in pH.
