Filiform Corrosion of Aluminum.

Abstract

Generally, filiform corrosion occurs on aluminum when it is coated with an organic coating and the system is exposed to relatively high humidities. This type of corrosion is initiated or activated by the presence of electrolytes, particularly chloride, and it is fostered by exposures to warm, humid environments. This type of corrosion is most intense where the coating is mechanically ruptured and discontinuous. Hence, in actual practice those places where mechanical fastenings are involved, filiform develops and produces delerious results. The problems of the mechanism of this kind of corrosion and the means of controlling or inhibiting this action have not been fully resolved, and the paper is directed toward these two aspects of the filiform corrosion of aluminum.
