Electrochemical behavior of Ti-6Al-4V alloy in static biosimulating solutions.

Abstract

The static general corrosion behavior of Ti-6Al-4V alloy specimens in three lactated Ringer's-based solutions was investigated using d.c. potentiodynamic, d.c. linear polarization resistance, and a.c. impedance techniques. A critical appraisal of the use of these techniques for the estimation of the corrosion rate of the material is presented. Whence it was shown that the presence of bovine serum in or decreasing the pH level of (to about 1) lactated Ringer's solution leads to an increase in the corrosion rate of the alloy (relative to that in lactated Ringer's solution, pH 6.25).
