Abstract
This article utilizes electrodeposition technology to fabricate Zn and Zn-Y2O3-Al2O3 composite coatings on Q235 steel plates. Composite coatings were obtained by adding nano Y2O3/Al2O3 particles (0, 5, 10, and 15 g/L) to acidic chloride solutions. The study examined the impact of nanoparticles on the microstructure, morphology, microhardness, hydrophobicity, and corrosion resistance of composite coatings. The results indicate that the addition of nanoparticles increases the nucleation sites on the surface of the coating, thereby refining the grain size and reducing the roughness of the coating surface. When the concentration of nanoparticles added is 10g/L Y2O3 and 10g/L Al2O3, the hardness of the composite coating (369 Hv) is 2.49 times higher than that of the pure Zn coating (148 Hv), which is attributed to the dispersion strengthening and grain refinement effects of the nanoparticles. The corrosion resistance of Zn and Zn-Y2O3-Al2O3 composite coatings was studied using linear sweep voltammetry and AC impedance spectroscopy. The addition of nanoparticles improved the corrosion resistance of the composite coating, and the composite coating prepared in an electrolyte containing 10 g/L Y2O3 and 10 g/L Al2O3 nanoparticles exhibited the best corrosion resistance. Meanwhile, the composite coating exhibits good hydrophobicity, with a contact angle of 120.9°, 1.94 times that of the pure Zn coating (62.2°). The Zn-Y2O3-Al2O3 nanocomposite coating material has significant potential advantages in the field of steel corrosion.
