| Tartalmi kivonat: | In this paper are presented preliminary results obtained using capsaicin extract as corrosion inhibitor for carbon steel in sodium chloride aqueous solution. Capsaicin is a chili pepper extract with analgesic properties. The electrochemical behavior of capsaicin in sodium chloride solution was examined by cyclic voltammetry Further, the inhibitory effect was studied by linear polarization and Tafel method in order to determin the kinetic parameters, providing informations about the the mechanism of inhibitory effect. The diminution of corrosion rate of carbon steel in the presence of capsaicin can be attributed to the inhibitor molecules adsorbtion on the sample surface and blocking the active sites, or depositing corrosion products on the metal surface. |
