The aim of this work is the study of the argon implantation on the corrosion resistance behavior of AISI 304 stainless steel substrates. The effect of ion implantation dose on morphology and corrosion properties of AISI 304 SS has been investigated.In this work, argon ions of 30 keV energy have been implanted into AISI 304 stainless steel at different fluences ranging from to Ar/cm2.The AFM analysis of implanted samples clearly shows significant change in surface. In order to evaluate the effect of the ion bombardment on the corrosion behavior, otentiodynamic tests were performed. The results show that the corrosion resistance of the samples strongly depends on the implantation fluences.The Corrosion potential and roughness curves obviously indicate that corrosion Potential variations caused by argon ion bombardment are inversely proportional to surface roughness. Corrosion current variations show an optimal dose at ions/ cm2 in which the corrosion resistivity is 12 times higher than un-implanted sample.
