A thin layer was formed on the surface of the AISI 316L substrate by the process of nitrogen ion implantation at a vacuum pressure of 10-6 torr, a current of 50 mA for 90 minutes with the implantation energy of 20, 40 and 60 keV. The purpose of this study was to investigate the effect of nitrogen ion implantation on corrosion fatigue resistance in Simulated Body Fluid solution as a corrosion medium. The results show that the nitrogen ion implantation could increase corrosion resistance by reducing the corrosion rate and increasing the number of fatigue cycles.
