N2  - Objective:
This research aims to determine corrosion behavior of SS316L biomaterial metals after plasma nitriding process.
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 ?-Cr2N phases were formed after nitriding process. Optimum corrosion
resistance (8.21 x 10-4 mm/yr) occurs at 350oC.
