Abstract
The present invention relates to a corrosion resistant metal article which comprises: (a) a metal body normally prone to corrosion when subjected to potentially corrosive conditions; and (b) a coating of neutral, undoped polyaniline in the emeraldine base form on a portion of the metal body (e.g., a side coating or undercoating) of the neutral, undoped polyaniline in the emeraldine base form on the metal body, where the distance (for example, not more than about one centimeter) between coated and uncoated portions of the metal is effective to protect the uncoated portion of the metal as well as the coated portion.
