	abstract = {The electrochemical behaviour of nitrogen ion-implanted Ti-5Al-2.5Fe was studied in HBSS-Hank{\textquoteright}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 non-implanted 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. {\textcopyright} 1997 Elsevier Science Ltd. All rights reserved.
