On Corrosion Behavior of Organic Nanocomposite Coatings

Recently, researches on composite coatings of organic nature with the addition of metallic oxide nanopowders have shown an increasing corrosion resistance of metallic materials. Carbon steel shows an improved behavior in corrosive environments when it is covered with an organic layer that includes...
