Abstract: 

This work presents the results of a low energy nitrogen ion implantation of AISI 304 type stainless steel (SS) at moderate temperatures of about 500oC. The nitrogen ions are extracted from a Kauffman type ion source at a Energy of 30 keV, and ion current density of 100 mA cm-2. In our study the nitrogen dose of 6×1017, 8×1017 and 1018 ions cm-2, were selected. The X-ray diffraction results show the formation of CrN polycrystalline phase after nitrogen bombardment and a change of crystallinity degree due to the dose effect the image analysis of implanted samples clearly shows significant changes in surface. Corrosion test has shown that corrosion resistance is enhanced by increasing dose.
