| Abstract: | Passive film formed on Fe-25Mn-5Al-0.15C alloy has been studied by X-ray photo-electron spectroscopy (XPS) after passivation in 30% NaOH solution.The results of depth-concentration profiles analysis by XPS indicate that the outermost surface and the main part of passive film present the bound water and a mixture of Fe 2O 3,Al 2O 3,Mn 2O 3,FeO( or Fe 3O 4)and MnO(or Mn 3O 4),respectively.The metallic Fe,Al and Mn coexist with their oxides in the passive film. |
