Abstract

In this study, the effect of Yttria and Benzotriazole doping on Corrosion behavior and activation of Self-healing mechanism in Alumina-based nanostructured coatings was investigated. Single-component Alumina, double-component Alumina-Ytteria, and triple-component Alumina-Ytteria-Benzotriazole ceramic-based coatings have been layer-deposited over St52 steel surface by the Sol-gel process in order to improve the abrasion and corrosion behaviour of this steel. Afterwards, phase analysis, morphology, and topography of these coatings have been carried out respectively by Grazing Incidence X-ray Diffraction (GIXRD), Field Emission Scanning Electron Microscopy (FE-SEM), and Atomic Force Microscopy (AFM). Moreover, in order to investigate elemental distribution in layer-deposited coatings, Energy Dispersive Spectroscopy (EDS) was performed. Also, the corrosion behaviour of under-investigation coatings and substrate were studied using electrochemical impedance spectroscopy and potentiodynamic polarization for 1, 48, and 96 hours of immersion in 3. 5wt%NaCl solution. GIXRD results revealed the amorphous nature of the coatings and the absence of formation of crystalline structure. AFM and FE-SEM observations revealed intactness of double-component Alumina-Ytteria and Alumina-Ytteria-Benzotriazole coatings in comparison with single component Alumina coating.
