Organically-modified silicate (Ormosil) films have been found to provide good corrosion resistance for 2024-T3, 6061-T3, and 7075-T6 aluminum alloy substrates. Significant enhancement in corrosion resistance properties of these films were observed upon addition of sub-micron to micron-sized TiO2 particles to the Ormosil coating as determined using accelerated salt spray and electrochemical analysis...
