| 4 | Description | Abstract | The corrosion study of mild steel in 1.0 M HCl solution at 298, 308 and 318 K using various concentrations of hexadecylamine as corrosion inhibitor for different immersion time were carried out by weight loss technique and other different techniques i.e. Potentiodynamic polarization, Electrochemical impedance spectroscopy (EIS) at 298 K and SEM techniques. The adsorption of this molecule leads to the formation of a protective layer on mild steel. From the weight loss measurement the maximum percentage corrosion inhibition efficiency 96.26% was observed for 1000 ppm concentration of inhibitor at 298 K. By electrochemical impedance study it observed that charge transfer resistance (Rct) value increases and double layer capacitance (Cdl ) value decreases with increasing the inhibitior concentration hence inhibition efficiency increases which related to the charge transfer resistance. From potentiodynamic polarization study it was observed that hexadecylamine behave as mixed type corrosion inhibitor. Adsorption of inhibitor on the mild steel surface is in agreement with the Langmuir adsorption isotherm. From the surface study it can be seen that on increasing the inhibitor concentration there is formation of protective layer on the surface of mild steel to protect the surface against corrosion and surface become smooth and more clean and clear. All above techniques study shows that hexadecylamine is a good corrosion inhibitor for mild steel in 1.0 M HCl solution. |
