Abstract
The motivation of these days working in the field of corrosion protection of metals is to replace the existing hexavalent chromium protection found to be carcinogenic with new methods using environmentally friendly technology. One of the alternative technologies is based on conductive polymers. The present publication presents to the reader the results of the effects of doping organic and inorganic ions (organic acids: camphor sulfonic acid (CSA), p-toluenesulfonic acid (p-TSA), phenylphosphonic acid (PPA), and oxalic acid (OA); and inorganic salt: cerium nitrate (Ce(NO3)3) into the polypyrrole coatings as to the development of corrosion protection coatings that offer to aluminum alloy substrate 2024-T3 protection. Beyond, we report coatings developed by the solution of p-toluenesulfonic acid with the electrochemical introduction of cations cerium, cobalt, and manganese.
