SEM - Opis:
- The inhibition of X80 carbon steel corrosion in 1 M HCl solution by dexketoprofen (DKP) was studied using weight loss (WL), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP) and scanning electron microscopy (SEM) techniques. The results indicated that DKP acts by way of adsorption as an effective protective inhibitor in the aggressive acid medium. The inhibition efficiency of DKP increased with concentration but was lower at higher temperature. The results of potentiodynamic polarization showed that DKP molecule behaved as a mixed type inhibitor by reducing both the anodic and the cathodic electrochemical reactions. Dexketoprofen was adsorbed on the X80 steel surface in accordance with Langmuir adsorption isotherm. SEM analyses supported formation of protective film on the X80 steel in the presence of DKP.
