Conclusions

  1. 1.

    Oxidation of the surface of iron-aluminum alloy at an oxygen pressure (PO2) < 10-7 torr leads to formation of a thin aluminum oxide film with high protective properties.

     
  2. 2.

    Oxidation of the alloy surface at (PO2) < 10-7 torr leads to formation of a ferric oxide film, underlain by a layer of aluminum oxide.
