The corrosion inhibition characteristics of aqueous extract of seeds of Melia
azedarach L (MA) have been studied as eco-friendly green inhibitor for corrosion
control of C-steel in 2 mol·L-1 HCl solution by gravimetric and electrochemical
methods. The results depicts that, the extract inhibit efficiently the corrosion of carbon
steel in hydrochloric acid. The efficiency of extract is increased with increasing the
extract concentration but independent on the studied temperature. The adsorption of
the extract components onto the steel surface were found to be spontaneous, and
follows Langimur adsorption isotherm. The surface morphology of C- Steel, in the
absence and presence of MA extract in 2.0 mol·L-1 hydrochloric acid solution, was
studied using scanning electron microscopy (SEM).
