Corrosion evaluation of Ti-48Al-2Cr-2Nb (at.%) in Ringer's solution.
Acta Biomater. 2006 Nov; 2(6):701-8.AB

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 degrees C and 800 degrees 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.
