Corrosion Inhibition of Rumex Vesicarius Extract on Stainless Steel 304 in Hydrochloric Acid Solution
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Stainless steel 304 (SS 304) is corrosion restraint in 2 M HCl by Rumex Vesicarius (RV) extract. This is studied using electrochemical (such as potentiodynamic polarization (PP), electrochemical frequency modulation (EFM) and electrochemical impedance spectroscopy (EIS)) and chemical (mass reduction (MR)) techniques at 25ºC. The extract was adsorbed on surface of SS and is consistent with Langmuir isotherm. The curves from PP indicate that RV extract change the anodic and cathodic Tafel lines. Such exchange led to RV extract play a mixed-kind. The parameters given from thermodynamic were measured from MR at various values of temperatures and were utilized to explain the mechanism of inhibitor. The 304 SS morphology of the coins was tested utilized AFM and ATR-FTIR.
