Abstract
A method of reducing corrosion, including coating a surface of a substrate with a corrosion inhibitor and drying to form a coated substrate. The coated substrate when contacted with a corrosive medium has a charge transfer resistance (Rct) of at least 2,000 kΩ. The corrosion inhibitor includes a sol-gel and limestone. The sol-gel includes reacted units of aminopropyltriethoxysilane (APTES), tetraethyl orthosilicate (TEOS), dimethoxy-methyl-octadecylsilane (DMMOS), vinyltrimethoxysilane (VTMS), and zirconium(IV) propoxide.
