Investigating the Acidic Corrosion Inhibiting Properties of Dryopteris Hirtipes on Mild Steel in Acidic Solutions
Subject area: Science,Engineering and Technology · Area of research: Corrosion
Abstract
The corrosion inhibition performance of ethanol extract of Dryopteris hirtipes (DH) on mild steel in 1 M HCl and 0.5 M H_2 ?SO?_4 solutions was studied using gravimetric and electrochemistry methods of corrosion monitoring. Computer simulation method was used to evaluate the relationship between the corrosion inhibition efficiency and the molecular structure of two active constituents of the inhibitor. The gravimetric results showed that corrosion inhibition efficacy increased steadily with concentration. Potentiodynamic polarization results revealed that the plant material functioned as a mixed type corrosion inhibitor for mild steel reducing both the anodic dissolution of metal and cathodic hydrogen ion reduction, electrochemical Impedance data and the computer simulation results confirmed that the corrosion reaction was retarded through the adsorption of the extract organic constituents on the mild steel surface.
