چکیده

Nowadays, zirconia based ceramic coatings are extensively used in various industries thanks to their favorable corrosion and wear resistance behavior. In this study, zirconia and zirconia-Benzotriazole nanostructured coatings were deposited on the surface of Al2024 to improve corrosion protection properties by using sol-gel method. Phases and morphology analyses were performed, and chemical bonds were investigated, using GIXRD, FTIR, AFM, FESEM and ellipsometry. In addition, corrosion properties were evaluated by electrochemical methods including polarization and electrochemical impedance techniques using a 3.5% NaCl solution. Results indicated a homogeneous and crack-free zirconia-Benzotriazole hybrid nanostructured coating which exhibited a good corrosion resistance at a corrosion current density reduced by a factor of 47683.
