| Abstract | ||||
| In this study, the inhibition effect of BESB6 Schiff base on carbon steelX52 corrosion in 0.5 M HCl solution was studied. For this aim, electrochemical techniques such as potentiodynamic polarization curves, weight loss (WL) were used. It was shown that, the BESB6 schiff base has remarkable inhibition efficiency on the corrosion of carbon steel in 0.5 M HCl solution. Polarization measurements indicated that, the studied inhibitor acts as mixed type corrosion inhibitor with predominantly control of cathodic reaction. The inhibition efficiency depends on the concentration of inhibitor and reaches 95% at.001M BESB6. The remarkable inhibition efficiency of BESB6 was discussed in terms of blocking of electrode surface by adsorption of inhibitor molecules through active centers. The adsorption of BESB6 molecules on the carbon steel surface obeys Langmuir adsorption isotherm. | ||||
