Abstract

A high-nitrogen containing face-centered-cubic phase (γ_Ν) formed on AISI 304L austenitic stainless steel surface via plasma source nitriding. The chemical composition of the passive film on the γ_Ν-phase was characterized by means of AES and XPS, which formed in a borax buffer solution with pH value of 8.4. The semi-conductive characteristic of the passive film on the γ_Ν-phase was investigated by Mott-Schottky analysis. The results showed that the passive film on the γ_Ν-phase was of a two-layered structure: of which the outer portion composed of iron hydroxide/oxides and chromium hydroxide/oxides exhibiting n-type semi-conductive and inner portion composed of mainly chromium oxides with a little chr-omium- and iron-nitrides exhibiting p-type semi-conductive. In comparison with the passive film on the plain stainless steel, the passive film on the γ_Ν-phase is much densified with lower donor- and acceptor-density and more negative of the flat band potential, thus leading to the lowering corrosion rate.

Key words: plasma source nitriding high-nitrogen face-centered-cubic phase passive film corrosion resistance property semi-conductive characteristic
