Abstract
Polyaniline (PANI) has been studied for some years in order to protect mild steels against corrosion in the absence of inorganic conversion layers. Du ring the electropolymerization of PANI film, iron is passivated; the subseq uent protection is dependent on the nature of this passive layer, and PANI acts as a stabilizer of this layer. The best conditions for PANI electrodep osition are discussed here, using a simple electrochemical test to characte rize the passivity breakdown. (C) 2000 The Electrochemical Society.
