This study reports the application of sol-gel coatings on aluminium alloy 2024-T3 substrates under electrochemical regimes and dip-coating process. Cerium-titanium oxide nanocontainers loaded with corrosion inhibitors 2-mercaptobenzothiazole and 8-hydroxyquinoline were incorporated into the coatings in order to improve the corrosion protection properties. Various silanes and silicones were used as precursors. The electro-deposited coatings were compared to coatings developed by dip coating process. Electrochemical impedance spectroscopy measurements were carried out in order the corrosion protection properties of the films to be evaluated. It was found that 3-glycidoxypropyltrimethoxysilane based films provided better protection against corrosion. The presence of nanocontainers improved the corrosion protection.
