摘要:

采用等离子体源渗氮技术在AISI 304L奥氏体不锈钢表面制备高氮面心结构的γ_Ν相层。利用AES和XPS分析了γ_Ν相层在pH值为8.4的硼酸溶液中钝化膜的化学组成,借助Mott-Schottky方程分析了γ_Ν相层钝化膜的半导体特性。结果表明：γ_Ν相层钝化膜具有双层结构,外层由Fe、Cr氢氧化物和氧化物构成,呈现出n型半导体特性;内层主要以Cr₂O₃为主,呈现出p型半导体特性,并且N以FeN_x和CrN_x形式存在于钝化膜内。与原始不锈钢钝化膜相比,γ_Ν相层钝化膜内施主浓度和受主浓度更低,平带电位负移,说明其钝化膜致密性更好,腐蚀速率更低。

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
