Corrosion behavior of a low modulus beta-Ti-45%Nb alloy for use in medical implants.

R Godley1, D Starosvetsky, I Gotman.   

Abstract

The corrosion and electrochemical behavior of a low stiffness beta -Ti-45wt.%Nb (Ti45Nb) was studied in solutions that resemble body environment, as compared to Ti6Al4V and Ti-55wt.%Ni (Ti55Ni, Nitinol) alloys currently used in surgical implants. In Ringers' solution, Ti45Nb alloy exhibited an excellent corrosion resistance, comparable to that of Ti6Al4V and much better than that of Nitinol. In acidic environments, beta -Ti45Nb remained passive under conditions where active dissolution was observed for both Ti6Al4V and Nitinol alloys. The results warrant further corrosion and biocompatibility studies of beta -Ti45Nb alloy to establish its suitability as implant material.
