摘要：
By the methods of chronopotentiometry and cyclic voltammetry, we study the electrochemical characteristics of Fe65.58Cr7.92Mn1.98Mo3.96V0.1Cu0.05W0.01Ti0.06C4.69Si2.85B5.94P6.93, Fe64.38Cr4.5Mo4V0.1C5P7B10Si2.87, and Fe68.93Cr2Mo4Mn(Cu,W, Al)(0.07)C7P10B5Si2 bulk amorphous metallic alloys in 0.5 M aqueous solutions of sodium chloride, potassium hydroxide, and hydrochloric acid. It is shown that the surfaces of the alloys in the indicated aggressive aqueous solutions are characterized by high corrosion resistances. As temperature increases, the corrosion resistance decreases in the solutions of sodium chloride and potassium hydroxide but remains practically invariable in hydrochloric acid.
