Corrosion behaviour of Ti-35Nb-7Zr-5Ta β titanium alloy nitrided by ion implantation was examined. Nitrogen ions were implanted with different fluences in the range from 1·1017 to 9·1017 cm−2 and an accelerating voltage of 90 kV. The specific effects of the nitrogen fluence on structural changes of the implantation zone showed the relationship between nitrogen concentration, nitride formation and corrosion behaviour. Nitrogen depth profiles measured by glow discharge optical emission spectroscopy showed the saturation limit approx. 60 at.% leading to the exo-diffusion of nitrogen.
