Corrosion Inhibition Effect of Pyrazole Carbohydrazide Inhibitor for AA 8088in1M H2SO4 Solution

The environmental friendly Pyrazole carbohydrazideinhibitor is synthesized and their corrosion inhibition for AA 8088in a 1 M H2SO4 solution was studied using weight loss methods, electrochemical measurements, and the surface morphology of AA 8088with 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 Pyrazole carbohydrazidewas excellent. Morphology observation revealed that the AA 8088was greatly protected by these Pyrazole carbohydrazideinhibitor.
