Cadmium plating has been used as a corrosion resistant coating for aerospace components for many years. Cadmium plating provides good corrosion resistance with excellent self lubricating properties. In spite of these properties, continuing efforts are underway worldwide to eliminate cadmium because of environmental concerns. Alternative processes are being investigated. Metallic - ceramic coatings which contain active aluminum metal powder as pigment have been proposed as cadmium replacements. These coatings have been in use for many years in air frame applications where cadmium plating could not be used because of part size, temperature exposure extremes, or part configuration. Examples of such components are described. Recently devised dense pack metallic-ceramic coatings show improved performance in which lower cure temperatures are possible and corrosion resistance is significantly upgraded when compared to original formulations.
