Abstract：A new surface modiffication technique by direct exposure of the native passive film on 1Cr18Ni9Ti stainless steel to electron cyclotron resonance (ECR) nitrogen plasma at room temperature was described.The modification significantly reduced its susceptibility to pitting corrosion. The pitting corrosion resistance of the modified steel in 1%NaCl solution was comparable to that of AISI type 316L stainless steel.In general, a higher self-biasing potential and a longer modification time resulted in further improvement of the corrosion resistance.The X-ray photoelectron spectroscopy (XPS) analyses showed that the modified passivating surface predominantly consisted of the stable Cr2O3,FeOx oxides, and other chromium oxides such as CrO3 and CrO2, as well as some of carboxyl species with a little chromium nitride. These chromium oxides were enriched in the modified passive films and could act as a stable corrosion resistant barrier layer.
