Title
Corrosion evaluation of Ti–48Al–2Cr–2Nb (at.%) in Ringer’s solution
Abstract

The corrosion behavior of Ti–48Al–2Cr–2Nb (at.%) in Ringer’s solution was studied to evaluate its potential as a biocompatible material. Corrosion properties of Ti–6Al–4V were determined under the same conditions for comparison. Two electrochemical techniques, potentiodynamic anodic polarization and electrochemical impedance spectroscopy, were employed to test Ti–48Al–2Cr–2Nb and Ti–6Al–4V. Surface modifications to the samples were made by autoclaving and by oxidation in air at 500 °C and 800 °C. The results show excellent corrosion resistance for unmodified Ti–48Al–2Cr–2Nb, corroborated by the high values of polarization resistance and corrosion potential and low values of corrosion current and corrosion rate. Ti–48Al–2Cr–2Nb appears to possess corrosion characteristics similar to Ti–6Al–4V. Surface modification rendered the Ti–48Al–2Cr–2Nb material extremely corrosion resistant.
