Abstract

A method for protecting a surface of an article includes preparing or otherwise providing a reactive solution of a form of polyaniline and an acid, thereafter applying the reactive solution to the surface of the article to form an adherent conversion coating on the surface, thereafter oxidizing the adherent conversion coating to form an oxidized coating, and thereafter contacting a chromate-free, corrosion inhibiting organic compound such as a salt of a dithiocarbamate or a salt of a dimercaptothiadiazole to the oxidized coating to form a fixed conversion coating on the surface of the article. The resulting article has the fixed conversion coating adhered to the surface of the article. The fixed conversion coating has a mixture of a reduced polyaniline salt, and a fixed disulfur-linked dithiocarbamate polymer or dimer.
