摘要:
A conductive polymer corrosion protective composite is provided which may be used as a coating for imparting corrosion protection to structures such as turbine engine components. The composite comprises an organic-inorganic component and corrosion inhibitive pigments comprising an anodic corrosion inhibitor and a cathodic corrosion inhibitor. The anodic corrosion inhibitor may be selected from the group consisting of compounds of vanadium, molybdenum, tungsten, and mixtures thereof. The cathodic corrosion inhibitor may be selected from the group consisting of cerium, neodymium, praseodymium, and mixtures thereof.
