Abstract
Sol-gel as protective coatings has been shown to exhibit excellent chemical stability combined with the ability to reduce the corrosion of metal substrates. The sol-gel method is an eco-friendly technique route for producing surface coatings, showing high potential for the replacement of toxic pre-treatment coatings. This study aims to develop a new understanding of the enhancement in corrosion protection of a hybrid-organic-inorganic sol-gel coating that cured at (80oC) by increasing the hydrophobicity and characterized the performance on the aluminium 2024-T3 alloy. The alternative method involved a novel sol-gel was prepared by introducing a 1H,1H,2H,2Hperfluorodecyltriethoxy silane (PFDTES) into the base hybrid sol-gel created from tetraethylorthosilicate silane (TEOS) and triethoxymethyl silane (MTMS) precursors. The results of electrochemical testing analyses reveal the new open finite-length diffusion circuit element (O) coming from electrolyte media diffusion preventive by fluorinated groups. Also, it is revealed increases in corrosion protection arising from the increasing the hydrophobicity of the fluorinated sol-gel coating when it compared to other formula cured under similar conditions. Additionally, the modified sol-gel exhibited improved resistance to cracking, while the increased hydrophobicity may also promote self-cleaning.
