Multifunctional composite coatings of Zn-ZnO-Cr2O3 were deposited electrolytically on prepared carbon mild steel (CS) from Zn electrolyte, having Zn2+ ions and uniformly dispersed nano ZnO-Cr2O3 particulates. The corrosion resistance characteristics of the deposited coatings were evaluated using the linear polarization measurement method in 3.65% NaCl. The microstructural properties of the produced multilayered coatings were evaluated by scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS), x-ray diffraction (XRD), and atomic force microscope (AFM). Thermal deformations were observed after 4h at 250 degrees C and the mechanical response of the coated samples was investigated using a diamond-based Dura Scan microhardness tester and a MTR-300dry abrasive wear tester. From the results, a significant improvement in the corrosion performance of coatings was observed with bath containing less than 2g/L. The microhardness, thermal stability, and anti-wear properties of Zn-ZnO-Cr2O3 shows improved performance against Zn-ZnO coating matrixes, which was attributed to dispersive strengthening effect and grain induced effect of the ZnO/Cr2O3 particulate.
