Methods: The plasma nitriding process on the surface of SS316L was performed at 350oC, 400oC, 450oC, 500oC, 550oC and 1.8 mbar nitrogen gas pressure for 3 hours. The surface Nitrogen concentration level distribution from the surface was examined using Energy Dispersive X-ray Spectroscopy, the phases formed after nitriding process were determined using X-ray Diffraction. The corrosion resistance was investigated using three-electrode cell polarization method. Result: The results showed that the percentage of nitrogen concentration atoms on the surface of the SS316L after plasma nitriding process was in range of 7.61-21.73\%, in which the highest number 21.73\% occurred at 500oC. Metal nitride formed on the surface of SS316L for all temperature variations are Fe4N, CrN and {\ensuremath{\beta}}-Cr2N phases were formed after nitriding process. Optimum corrosion resistance (8.21 x 10-4 mm/yr) occurs at 350oC. Keywords: Plasma nitriding, SS316L, Biomaterials, Corrosion resistance, Nitrogen, Fe4N} }
