چکیده
|
The corrosion inhibition of copper cda 110 in 3% nacl by ruta chalepensis’ extract is studied by using electrochemical stationary and non-stationary methods. the obtained results reveal a significant enhancement of the inhibition efficiency by increasing the extract concentration. the adsorption behavior is found to obey langmuir isotherm. polarization study shows a cathodic character for the green leaves. the increase of medium temperature accelerates the corrosion process. the values of activation energy and thermodynamic parameters are calculated. in-depth the first principles calculations based on density functional density have been performed in order to evaluate the electronic structure and to understand the corrosion mechanism.
