摘要

The thin films of Vanadium Pentoxide nanoparticles (V2O5) were deposited on an Aluminium alloy-6061 (Al-6061) substrate by Sol–gel process through a spin coating technique. The film’s phase, purity, crystal nature, surface morphology, and elemental mapping of V2O5 thin film on Al-6061 substrate were obtained via X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray analysis. They also examined their anticorrosive properties through the weight loss method, electrochemical measurements such as Potentiodynamic Polarization, and Electrochemical Impedance Spectroscopic studies under various environments by immersing the substrate in acid chloride, acid sulfate, acid nitrate, and neutral chloride medium at room temperature. The obtained results reflect the improvement in the surface property against the corrosion in terms of corrosion resistance of the V2O5 thin film-coated Al-6061 substrate compared to that of the bare substrate.
