| Abstract | ||||
| Corrosion is the most serious problem that opposes alloys and metals, and it leads to many industrial issues, such as the deterioration of structures and equipment and corrosion in factory tanks and pipelines in petroleum refineries, which shortens the lifespan and reduces the efficiency of such systems. Inhibitors are therefore applied to corrosive media via effective ways in order to improve the corrosion inhibition of metals and alloys.in the present work. The present work prepared a compound N-((2-aminoethyl) carbamothioyl)benzamide by green chemistry procedure then evaluate the prepared compound as corrosion inhibitor by electrochemical methodologies Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic Polarisation (PP) techniques and found that the prepared inhibitor has the adsorption ability over the carbon steel (CS) and it has the double layer capacitance( )value was often less than in its absence, owing to the synthesized inhibitor's effective adsorption.so the prepared compound N-((2-aminoethyl) carbamothioyl)benzamide has binary effect first prepared by green chemistry and the second one is the prepared compound has good efficiency as corrosion inhibitor so make long life time for the surface of Carbon Steel Alloy. Key words: green chemistry; thiourea derivatives; corrosion inhibitor; EIS; potentiodynamic polarization. | ||||
