Abrasion and Cavitation Erosion Resistance of Multi-Layer Dip Coated Sol-Gel Coatings on AA2024-T3

AA2024-T3 are widely used in various applications because of their exceptional physical properties. However, they susceptible to corrosion and cavitation erosion aggressive environments due high concentration copper. Sol-gel coatings the field prevention emerging. Improved thickness significantly improves barrier effect coatings, thereby improving operational-life industrial applications. To date, a limited amount work has been carried out determining hybrid sol-gel on abrasion AA2024-T3. The present study investigates morphology, corrosion, properties prepared deposited surfaces. sol-gels have synthesized from 3-trimethoxysilylpropylmethacrylate (MAPTMS), zirconium complex chelation n-propoxide (ZPO), methacrylic acid (MAAH). AA-2024 T3 were coated using single-dip, double-dip triple-dip. Abrasion tests performed according relevant standards. Structural damage caused by was studied Optical Microscope Scanning Electron (SEM). Corrosion protection performance tested Open Circuit Potential (OCP) Potentiodynamic polarization (PDS). Results indicated that multilayer samples improved resistance Hence, silica-based can be proposed as potential choice for marine renewable energy
