Effect of deformation on corrosion behavior of Ti–23Nb–0.7Ta–2Zr–O alloy

The influence of deformation on the corrosion behavior of a newly developed multifunctional beta titanium alloy Ti–23Nb–0.7Ta–2Zr–O (mol%) in Ringerʹs solution at 310 K was evaluated using an electron backscatter diffraction technique and electrochemical measurements. The results showed that the effect of deformation on the corrosion resistance of the beta titanium alloy is complicated. Small levels of plastic deformation are detrimental to the corrosion resistance, whereas large deformations tend to eliminate this detrimental effect.
