Application of Mossbauer Spectroscopy of Conversion and Aug Electrons for the Study of Transformations on Fe Electrode under Conditions of Passive—Transpassive Transition

摘要

Using Mossbauer spectroscopy of conversion and Auger electrons and X-ray photoelectron spectroscopy peculiarities and regularities in formation of composition and structure of the products of oxidation of ~(57)Fe samples in solutions of 0.1 N NaOH, a mixture of 1 N NaOH and 6 N NaNO_3, 1 N H_2SO_4, 0.1 N H_3BO_3, and 0.5 mol/L Na_2B_4O_7 in relation to the nature of corrosion medium and charge densities of anode polarization (10... 12000 mA/cm2) corresponding to the region of passive—transpassive transition has been studied.
