Abstract

Ti and Ti alloys are important materials for medical and dental applications. The effect of equal channel angular process(ECAP) and addition of Fe in Ti were studied with optical microstructure and corrosion behavior. Fine grains in Ti was obtained after ECAP. Corrosion behavior of commercial pure(CP)-Ti and Ti alloys was studied by open circuit test and polarization curve test(PCT) at $36.5^{\circ}C$ with SBF in biological environment. The corrosion behavior of ECAP-Ti was similar to that of CP-Ti in PCT, but Ti-Fe alloys were observed to become more corrosive with increasing Fe content.
