Abstract
Since Zn–Ni alloy coatings are more resistant to corrosion than pure zinc coatings, they are being researched extensively. In this study, Zn–Ni alloy coatings electrolytically deposited from an acidic sulfate bath are investigated. The study looks into how the microstructure, phase composition, and corrosion resistance of the coatings are affected by deposition factors like pH, current density, and electrolyte composition. X-ray diffraction (XRD), potentiodynamic polarization, and scanning electron microscopy (SEM) were used to characterize the coatings. According to the results, a Ni content of 10–15% in the alloy causes a γ-phase to develop, greatly increasing corrosion resistance. Coatings that were homogenous, adhesive, and extremely corrosion-resistant were produced by the ideal deposition conditions. The results offer a means to create Zn–Ni coatings with superior performance for industrial uses. With an emphasis on the impact of deposition parameters on the coating's microstructure, phase composition, and corrosion resistance, this study attempts to investigate the electrolytic deposition of Zn–Ni alloy coatings from an acidic sulfate bath. The project aims to create Zn–Ni coatings with improved performance for industrial applications by refining the deposition conditions. The findings of this study will open the door for the creation of high-performance Zn–Ni coatings by offering insightful information on the connection between coating characteristics and deposition parameters.
