The present invention relates to metal surfaces having thereon an
ultrathin (e.g., less than ten nanometer thickness) corrosion-resistant
film, thereby rendering the metal surfaces corrosion-resistant. The
corrosion-resistant film includes an at least partially crosslinked
amido-functionalized silanol component in combination with rare-earth
metal oxide nanoparticles. The invention also relates to methods for
producing such corrosion-resistant films.
