چکیده انگلیسی
The inhibitive action of Santolina chamaecyparissus extract as a natural inhibitor on corrosion of 304 stainless steel in 3.5% NaCl solution was investigated by potentiodynamic polarization, EIS, and SEM techniques. The results indicate that the extract shows mixed-type inhibition behavior and inhibition efficiency of 86.9% was achieved with the addition of 1.0 g L−1 extract. Impedance curves show that increasing Santolina concentration increases charge transfer resistance and decreases double layer capacitance. The corrosion rate decreased with increasing concentration of extract and increased with the increase in temperature of the medium. Adsorption of the extract obeyed the Langmuir isotherm model.
