Corrosion is one of the most expensive failures in industries that used metal components and other construction materials. In fact, corrosion is responsible for hundreds of billions-dollar loss in the US alone each year. In general, corrosion occurs when metal surfaces are exposed to water, oxygen, acids, bases, or salts. Therefore, metal substrates must be protected by using materials that act as barriers to avoid destructive corrosion attack. Aluminum is one of the most common metals used in the industry; and it is used in many places such as refining and petroleum production equipment, pipelines, and fossil fuel power plants. Aluminum is known to have corrosion resistance due to the forming of an oxide layer that can be reformed rapidly if the surface gets damaged. However, in the long-term the oxide layer cannot protect the aluminum surface from corrosion because it is stable only in neutral mediums and it is soluble in acidic and basic environments. Barrier protection is one of the most effective methods that prevent aluminum surfaces from being exposed to corrosive environments. These barriers can be organic or inorganic coatings that can limit the electron transport or the cathodic and the anodic reactions between aluminum alloys and the surrounding environment. Fluorinated polymers that were used in this study exhibit excellent properties which make them good candidates for corrosion protection applications. These properties include high hydrophobicity which is responsible for repelling oxygen and water and reducing the wettability of the metal surface, strong adhesion to the metal surface allowed for covering and protection of substrates in aggressive environments, and thermal stability that allows for using these polymers in high temperature environments. Overall, the corrosion protection, which was evaluated using electrochemical techniques, and the mechanical properties were improved with these fluorinated polymeric coatings in comparison to the bare aluminum alloys which proves to be advantageous for using these polymeric coatings in many areas including marine environments, oil and gas industries, and fossil fuel power plants.
