Aluminum Pigments Encapsulated by MTES and TEOS for Corrosion Inhibition and their Characterizations

Abstract:

Aluminum pigments were encapsulated by hydrolysis and condensation of tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES). The influences of solvents and ratio of MTES/TEOS on corrosion inhibition performance were studied. The FTIR, XPS and SEM analysis showed that both TEOS and MTES hydrolyzed and condensed at the same time to form a compact and thin sol-gel layer on the surface of aluminum pigments. Aluminum pigments encapsulated by MTES and TEOS, which can hardly generate H₂ in acid media of pH=1 within 12h, show greatly excellent corrosion resistance than that only by TEOS or by MTES, due to the formation of a compact and thin hybrid film to protect aluminum particles from corrosive media.
