摘要: 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 depict that, the extract inhibits 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 was found to be spontaneous, and follows Langmuir adsorption isotherm. The surface morphology of C-steel, in the absence and presence ofMA extract in 2.0 mol·L-1 hydrochloric acid solution, was studied using scanning electron microscopy (SEM).
