bstract: In this integrated study, the project aims to develop a novel hybrid green metal matrix composite using stir casting, reinforcing aluminum alloy with Waste materials such as Waste Carbonized Eggshells (WCE), Cow Dung Ash (CDA), Snail Shell Ash (SSA), and Bamboo Leaf Ash (BLA) The experiment incorporates various organic-inorganic mixed coatings, including vinyltrimethoxysilane (VMS), 3-(methacryloxy)propyl trimethoxy silane (MPMS), and (3-glycidoxyproyl) trimethoxy silane (GPMS), combined with tetraethoxysilane (TEOS), to enhance corrosion resistance. Potentiodynamic polarization curves, SEM images, and salt spray tests are employed to assess coating durability against corrosion. Results indicate significant reductions in corrosion flow with VMS and MPMS coatings, particularly with a 15-20% TEOS ratio, showcasing optimal corrosion resistance against salt spray. This innovative approach combines material recycling and advanced coating techniques to produce a sustainable composite with improved mechanical properties and corrosion resistance.
