ABSTRACT:
The invention relates to a process for depositing a thin adhesive coating of polypyrrole on the surface of an article made of oxidizable metal, by electropolymerization of an aqueous or aqueous-alcoholic electrolytic solution of pyrrole and/or of one or more substituted pyrroles, in which the anode of the electropolymerization device consists of the article made of oxidizable metal, in which the solution contains ions selected from the ions of formula: ##STR1## in which X is selected from O, S and NH,
