Abstract Scope |
High Entropy Alloys (HEAs) are advanced materials known for their exceptional mechanical and wear properties, as well as improved corrosion resistance. FeCoNiCuZn is a recently studied HEA that shows enhanced charge storage properties for supercapacitor applications. However, the performance of HEAs is influenced by their degradation rates. In this study, FeCoNiCuZn HEA is prepared via induction melting, and its corrosion behavior is thoroughly investigated. Electrochemical impedance spectroscopy, potentiodynamic polarization, and cyclic polarization techniques are performed using different electrolytic solutions (H2SO4, NaCl, and KOH) at varying concentrations (0.1M and 0.6M). The results indicate that the electrochemical properties of the HEA are significantly affected by the electrolyte medium and its concentration. The HEA demonstrates improved corrosion resistance and passivation in KOH media, whereas a decline in corrosion resistance is observed in H2SO4 and NaCl media. Post-corrosion analysis confirms the susceptibility of the HEA system to dezincification. |
