  • Role of Nitrogen in Pitting Corrosion Resistance of a High

    2005-7-6 · The role of nitrogen in pitting corrosion resistance of Fe-Cr-Ni austenitic stainless steel was investigated using a high-nitrogen face-centered-cubic phase formed on the plasma source ion-nitrided 1Cr18Ni9Ti (18-8 type) austenitic stainless steel. No pitting corrosion for the phase layer was confirmed by electrochemical polarization measurement in 3 NaCl solution.
