Abstract Scope |
Additive manufacturing revolutionizes materials science by creating complex structures with unique features, including high-entropy alloys. In this study, we present a comprehensive characterization of additively manufactured AlCoCrFeNiCu and AlCoCrFeNiTi HEAs using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) technique as a powerful electrochemical technique. The objective of this research is to investigate the electrochemical behavior of these HEAs to gain insights into their underlying mechanisms and potential applications in corrosion-resistant coatings. The alloys were fabricated via a powder laser metal deposition technique, and the cyclic voltammetry experiments were performed in an electrochemical cell with a sulfuric acid electrolyte to explore the alloys' electrochemical response. The results reveal distinct electrochemical characteristics for AlCoCrFeNiCu and AlCoCrFeNiTi HEAs. The CV curves exhibit well-defined peaks and plateaus, indicating the occurrence of multiple electrochemical reactions. The results from EIS complement the CV findings providing additional information on the alloys' charge transport and interfacial properties. |
