Evaluation of improved corrosion resistance of Zn alloy as electrode material by Co3O4 coatings
This work uses the sonochemical method to represent synthesized cobalt oxide nanoparticles (Co3O4) and analysed using different techniques. The X-ray diffraction analysis (XRD) and Fourier-transform infrared spectroscopy (FTIR) examinations of the synthesized nanoparticles confirmed their cubic structure and average crystallite size of 21.3 nm. The spherical surface shape and presence of components with a particle size of 25.3 nm were revealed. Scanning probe microscopy (SPM) methods analysed the Co3O4 coated plates' surface characteristics, including roughness and topographical ideas. An aqueous electrolyte medium (6 M KOH) was used to investigate the electrochemical corrosion behaviour of Co3O4-coated plates. According to the Tafel plot, coating Zn plates with a high surface area and mesoporous Co3O4 in KOH electrolytes greatly reduced the corrosion of the plates. The coated plates are thermally treated up to 600℃. The temperature-dependent anticorrosive properties of Co3O4 NPs are evaluated. KEY WORDS: Co3O4, Zn plate, Tafel plot, Linear sweep voltammetry, Anti-corrosive performance, Nanoindentation Bull. Chem. Soc. Ethiop. 2024, 38(1), 241-253.
