摘要：

A Ti-Al-V alloy was implanted with Al and Nb to flounces ranging from 1 x 10(17) to 1 x 10(18) ions cm(-2). Glancing Angle XRD measurement revealed alpha-Ti on Al-implanted samples and (alpha+beta)-Ti on Nb-implanted samples. The (alpha+beta)-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.
