Corrosion inhibition of low carbon steel in 1 M HCl solution using Pulicaria undulata plant extract
Pulicaria undulata (PU) plant extract was assessed as low cost, green and effective
dissolution inhibitor for low C-steel (LCS) in 1 M HCl medium using mass reducing method,
gasometric method, electrochemical impedance spectroscopy (EIS), Tafel polarization
methods, EFM as well as surface studies by XPS, SEM and AFM techniques. Increasing PU
extract concentration raises the R ct and drops the C dl as a result of the PU extract
adsorption on the alloy surface. The polarization results showed the mixed-type inhibition …
