The 0.01-0.02 % NaNO2 + 0.01-0.02 % tetraethylammonium perchlorate composition in the в defatted water was proposed for corrosion defense of AMA's surface. It determined that (С2Н5)4N+-ion forms the hydrophobic dynamic barrier on the electrode-solution boundary, which is a good anticorrosion factor in the results of the oxygen absorption. The stability of produced layers from the solutions of hetrofunctional oligomers on the basis of 2-tert-butylperoxy-2-methyl-5-hexen-3-in and maleic anhydride and also 3-tert-butylperoxy-3-phenylbutyl methacrylate and its metallocomplexes depends from the nature and concentration of film-forming compounds and from the duration of immersion in the solution. It was determined that the most dense layers forms from the 0.1-0. 5% olygoperoxides aqueous-ammoniac solutions on the preliminarily oxidized surface of Fe- and Co-based alloys.
