Iron Corrosion in the Radiative Plasma of Moist Air

Abstract The rate of iron corrosion in a low-temperature plasma moist air formed under the action fast electron beam, depending on relative humidity, was measured. It is shown that beam electrons (radioactive β-radiation) significantly intensifies plasma-forming gas medium which oxygen and water vapour are simultaneously present. has been established conditions radioactive irradiation increases sharply when humidity exceeds 10%. Numerical simulation ionic composition carried out taking into account 12 types positive negative hydrated ions at different intensities external ionization source values from 10 –6 to 100%. A hypothesis put forward about determining role cluster ions, atmospheric pressure, heterogeneous processes oxidation.
