Abstract
In this work, design and preparation of different hybrid ceramic coatings based on Diglycidyl ether of Bisphenol A (Epoxy) and 3-Glycidyloxypropyl trimethyloxysilane (GLYMO) by sol-gel technique was studied. The obtained hybrids coatings were cured by using different hardners. Microstructure assessment of the prepared hybrids was investigated using FTIR. The morphology of the hybrid (silica/epoxy) coatings has also been studied by scanning electron microscopy (SEM). Evaluation of selected mechanical properties (adhesion, and hardness) were performed. In addition, the thermal properties were investigated using thermogravimetric analysis (TGA). The investigation of the different prepared coatings for protection against corrosion were studied based on EIS measurements. The results showed that the silica content plays an important role in determining the morphology as well as the mechanical and thermal properties of the coatings. The EIS results showed an improvement in the corrosion resistance of the hybrid coatings with increasing the silica content up to a certain extent. However, further increase in the silica content, leads to a descent in the corrosion resistance.
