Characterization of Co–Cr–Fe–Mn–Ni High-Entropy Alloy Thin Films Synthesized by Pulse Electrodeposition: Part 2: Effect of Pulse Electrodeposition Parameters on the Wettability and Corrosion Resistance

Abstract

Co–Cr–Fe–Mn–Ni high-entropy alloy thin films were synthesized by pulse electrochemical deposition method. The films were co-deposited in an electrolyte based on a DMF-CH3CN organic system consisting of Co, Cr, Fe, Mn, and Ni cations via the pulse electrodeposition method at 2500 and 5000 Hz frequencies, as well as 50% and 60% duty cycles. The GXRD patterns indicated that films consisted of a single face-centered-cubic structure. The effect of pulsed electrodeposition parameters on wettability and corrosion resistance of coatings was investigated as well. The results of the hydrophobic/hydrophilic test showed that all coatings were completely hydrophilic; the largest wettability angle is for the prepared film at a duty cycle of 50% in frequency of 5000 Hz (56°). The potentiodynamic polarization test results showed that same sample with a corrosion density of 0.067 μA/cm2, improved the corrosion resistance of the substrate due to the superhydrophilic properties of those by about 34 times, and therefore, was chosen as optimal conditions. Also, it was shown that none of the samples were sensitive to pitting corrosion. The results of the EIS test showed an outstanding performance of coatings in improving corrosion resistance compared to similar alloy samples, with a conservation efficiency of about 95%. In addition, it enables the evaluation of continuous changes in the metal-coating system. In such conditions, prepared film at 50% duty cycle in frequency of 5000 Hz improved the corrosion resistance of the substrate by about 40 times.
