摘要：

The corrosion resistance of AN SAE 4140 steel implanted with nitrogen ions was studied by using the technique 3DII (Three Dimensional ion implantation). Different roughness of the samples implanted by electrochemical techniques as Rp, EIS and Tafel in a 3% NaCl brine, were evaluated, obtaining the best corrosion resistance for the material implanted with lower roughness. There was the formation of a possible protective layer stable with the immersion of the samples in the electrolyte for experimental time above 240 hours.
