Analysis of Corrosion Resistance Behavior of Green Inhibitors on Mild Steel in 1N HCl Medium Using Electrochemical Techniques

Author(s): K. Vishalakshi, P. R. Sivakumar and A. P. Srikanth

The use of Balsamodendron Caudatum (BC) leaves extract as mild steel corrosion inhibitor in 1N HCl medium was investigated using weight loss, potentiodynamic polarization methods and Electrochemical Impedance Spectroscopy and characteristics analysis by Fourier Transform Infra-Red (FTIR). Obtained data from weight loss polarization methods, impedance suggested that the value of inhibition efficiency (% IE) was proportional to added inhibitor concentration. Tafelconstants data indicated that BC extract can act as mixed type inhibitors. The surface morphology was determined using Scanning Electron Microscopy.
