Surface Characteristics and Corrosion Behavior of Ti-4Al-2V Alloy Implanted with Al and Nb

Abstract:

Article Preview

A Ti-Al-V alloy was implanted with Al and Nb to flounces ranging from 1 × 1017 to 1 × 1018 ions cm-2. Glancing Angle XRD measurement revealed α-Ti on Al-implanted samples and (α+β)-Ti on Nb-implanted samples. The (α+β)-phase samples exhibit better corrosion resistance. In the aerated solution with pH = 10, all the implanted surfaces are passive. Enhanced reoxidation was confirmed on implanted surfaces by Auger electron spectroscopy and X-ray photoelectron spectroscopy analysis. The corrosion in the solution with pH = 10 was governed predominantly by a TiO2 surface film.
