Abstract

The corrosion resistance of high-entropy Fe–Cr–Co–Ni–Mn alloy plates obtained by cold rolling using a Kvarto-110/320 × 300 mill in a 3.5%-NaCl aqueous solution has been analyzed. The effect of the compression degree of 40, 60, and 80% on the structure, corrosion potential, and corrosion current density has been studied. It has been determined that at an increase in the compression degree from 40 to 80%, the overall corrosion resistance increases, which is determined by a decrease in the corrosion current density from 3.98 × 10–8 to 2.90 × 10–8 A/cm2. The obtained results indicate the possibility of regulating corrosion resistance by plastic deformation.
