Abstract (EN): The electrochemical behaviour of nitrogen ion-implanted Ti-5Al-2.5Fe was studied in HBSS-Hank's balanced salt solution, by open-circuit potential vs time and cyclic polarization techniques. Three fluences (10(15) 10(16) and 10(17)ions/cm(2)) were used. All ion-implanted surfaces showed higher corrosion resistance than the nonimplanted ones. The corrosion potential of the ion-implanted samples was more noble and their passivation current was lower than the non-implanted ones. X-ray photo-electron spectroscopy showed that the immersion of Ti-5Al-2.5Fe in HBSS produces a Ca- and P-rich surface layer. (C) 1997 Elsevier Science Ltd.
