The corrosion behavior of metals in nature environment is a spontaneous process from the viewpoint of the chemical thermodynamics, which can result in destructure and function-loss of metallic materials. Among the corrosion protection methods of metals, such as electrochemical protection, treatment of corrosive media and coatings protection, organic coatings is one of the most frequent applications at the present time. The corrosion of coated-metals is closely related to organic coatings performance. Howeve...
