摘要
By the methods of chronopotentiometry, cyclic voltammetry, and electrochemical impedance spectroscopy, we investigate the corrosion resistance of alloys based on Fe in aqueous solutions of H2SO4 of different concentrations. It is shown that, as the potential scanning rate and the time of contact with aggressive media increase, the corrosion potentials shift in the anodic direction. On the basis of the results of electrochemical investigations, it is shown that alloys with additions of Cu, Nb, Ni, Cr, and Mo are more corrosion-resistant and that the modification by alternating magnetic fields improves their corrosion resistance.
