Green Corrosion Inhibition Of Mild Steel By Asafoetida Extract Extract In 3.5% NaCl
Published 2019 · Materials Science
Abstract Corrosion is the deterioration of a metal by chemical or electrochemical reaction with its environment. It is impossible to eliminate corrosion completely. So prevention would be more practical than elimination. There are several methods to effectively control and minimize corrosion. The small quantity of corrosion inhibitors can effectively decrease the corrosion process. Mild steel is a material of used in industries due to easy availability and fabrication of machineries. Corrosion can damage the materials which are used to construct automobiles, pipeline systems, bridges and buildings, petroleum refineries, etc. Plant extracts have been recently studied as corrosion inhibitors for different metals in various environments. In the present work, an aqueous extract of asafoetida have been used as a corrosion inhibitor in controlling corrosion of mild steel. The formation of protective layer on the surface of metal are to be confirmed by FTIR, XRD and SEM. The corrosion inhibition of mild steel have been be studied by potentiodynamic polarization and electrochemical impedance spectroscopic techniques.
