The environmental friendly 1-(4-Methoxy-phenyl)-3-(5-phenyl-1,3,4-oxadiazol-2-yl)propan-1-one (A1) inhibitor is synthesized and their corrosion inhibition for Mild Steel in a 1 M HCl solution was studied using weight loss methods, electrochemical measurements, and the surface morphology of mild steel with and without inhibitor were studied using scanning electron microscopy (SEM) analysis. The inhibition efficiency of 1-(4-Methoxy-phenyl)-3-(5-phenyl-1, 3, 4-oxadiazol-2-yl) propan 1-one improved with increases in inhibitor concentration but decreased with increases in temperature. Results from potentiodynamic polarization and EIS showed that the corrosion inhibition efficiency of 1-(4-Methoxy-phenyl)-3-(5-phenyl-1, 3,4-oxadiazol-2-yl)propan-1-one was excellent. Morphology observation revealed that the Mild Steel was greatly protected by these 1-(4-Methoxy phenyl)-3-(5-phenyl-1,3,4-oxadiazol-2-yl)propan-1-one inhibitor.
