The Influence of the Composition of Amorphous Alloys on Their Corrosion Resistance in Aggressive Environments of Different Nature
The influence of the elemental composition of strip amorphous alloys Fe80.0Si6.0B14.0, Fe78.5Ni1.0Mo0.5Si6.0B14.0; Fe73.1Cu1.0Nb3.0Si15.5B7.4; Fe51.7Ni21.7Cr6.2Mo0.6V1.5Si5.2B13.1 on corrosion resistance in 0.5 M aqueous solutions of NaCl, HCl, and KOH at T = (293 ± 1) K was investigated. The high corrosion resistance of Fe51.7Ni21.7Cr6.2Mo0.6V1.5Si5.2B13.1 and Fe73.1Cu1.0Nb3.0Si15.5B7.4 alloys in aggressive environments was established. Electrochemical parameters obtained both by the method of cyclic voltammetry and electrochemical impedance spectroscopy (EIS) indicate the formation of more durable surface layers in a 0.5 M potassium hydroxide aqueous solution on these alloys. The Cl– ions (especially at low pH) under their long-term action are the more aggressive oxidizers of amorphous alloys compared to OH– ions. During the passivation film formation in highly aggressive environments such alloy elements, which do not participate in this process, actively dissolve, and the main film-forming elements accumulate under the film, thus improving its protective properties.
