摘要
以俄歇电子谱仪与Ｘ射线光电子谱仪研究了Ｆｅ—２３Ｍｎ一５Ｃｒ合金表面在ＩＭＮａ２ＳＯ４水溶液中所形成的钝化膜．实验结果说明：①钝化膜的外层富含氧，钝化膜的中层富含铬与锰；②在钝化膜中，铬、锰与铁分别呈Ｃｒ３＋，Ｍｎ３＋，Ｆｅ３＋及Ｆｅ０，氧形成Ｍ—Ｏ键；③钝化膜很可能由Ｃｒ２Ｏ３，Ｍｎ２Ｏ３，Ｆｅ２Ｏ３与微量金属铁混合组成．
The passive film formed on the surface of Fe-23Mn-5Cr alloy in iM Na2SO4 aqueous solutinn has been investigated by the Auger electron spectrometer and X-ray photoelectron spectrometer.The results show that:(1)the outer pert of the passive film is enridied in chromium and manganese;(2)chromium is present in the passive film as Cr3+,manganese as Mn3+,iron as Fe3+and Fe0 and oxygen in M-O bond and(3)the passive film is probably made up of a fixture of Cr2O3,Mn2O3,Fe2O3and Fe0.
