AbstractIn the present investigation, the static electrochemical corrosion behavior of nano (Al2O3)P based aluminum in Al –Fao water with and without inhibitor was compared. The nanocomposites were fabricated by using liquid metallurgy technique. The effect of inhibitors for nanoparticulates weight percentage on the corrosion rate was studied. The corrosion rate was increased by increasing weight percentage of the nanoparticles, the Al/ 5% nano (Al2O3)P composites exhibited the highest corrosion resistance among all the investigated nanocomposites with and without inhibitors. The obtained results signified that the mechanism of adsorption of thiourea molecules on the MMC surface was by physisorption.
