| description | One of the most common ways of protecting metals from corrosion is to form a film on metal surfaces or to
coat them with suitable materials. Thus, metals are protected from corrosive components in their environment. However, in the case of openings at the micro level that may occur in the formation of the coating or in case of scratches and similar openings that may occur after the coating, water and air will reach the metal surface and initiate corrosion. In
this study, the effect of polypyrrole (PPy), polyaniline (PANI) and MoS2 doped PPy and PANI coatings on the corrosion rate of steel was investigated. Corrosion resistance of these coatings was determined by measuring corrosion rates by Tafel Polarization method in 0.1 M NaCl medium. Because of the experiments, it was determined that these homogeneous and adhering coatings were effective against corrosion. The best protection against corrosion was found as 96.7%, 89.0%, 69.5% and 45.2% for PPy + MoS2, PPy, PANI + MoS2 and PANI coatings, respectively. MoS2 additive yielded positive results for both coatings. Better protection of PPy than PANI can be explained by the fact that the oxidation potential of pyrrole (0.6 V) is lower than the aniline oxidation potential. |
