Abstract

This study investigates the formation of nanocomposites on zinc substrates through the electrochemical process of zinc foil in sulfuric and phosphoric acid at room temperature. After immersing pure Zn into a solution containing 3.6g CuO in 15% H2SO4, ZnO and CuO microstructures were created. XRD and AFM techniques were used to characterize the thin films and 3-D microstructures. The (CuO-ZnO) composite had nanoscale size and an average of 68.78932nm, with ZnO having a wurtzite and zincite structure, and CuO crystals having a tenorite structure. The study also discusses the effects of the development and modification of CuO nanoparticles in a multi-bath as stabilizers and surfactants on the Zn morphology. The deposits with added CuO had larger particle sizes and thicker deposits, while the multi-bath in H3PO4 resulted in a more compact, thicker, and dense structure on the surface. The study also found that using more than one phase resulted in a protective, adherent, uniform, and plate-like morphology of the corrosion products.
