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, other than stainless steel or a metal similar to stainless steel; and (b) a neat coating of neutral, undoped polyaniline in the emeraldine base form on the metal body.
