摘要：

Variable angle XPS studies of the passive films formed on the alloys Fe-19Cr-9Ni and Fe-19Cr-9Ni-2. 5Mo in deaerated 0. 1M HCl is presented. The complex spectra contains two major peaks with positions corresponding to Cr//2O//3 and CrOOH or Cr(OH)//3. Two minor peaks corresponding to CrO//3 and CrO//4**2** minus are also found. For each alloy the Cr//2O//3 phase appears to be situated at the metal-film interface. Independent studies indicate that CrO//3 is incorporated in Cr//2O//3 and that CrO//4**2** minus is incorporated in the Cr(OH)//3 or CrOOH phase. The outer layers of the anodic film in each case contain iron hydroxy-oxides.
