Description THE EFFECTIVENESS of several inhibitors towards corrosion of AA 6061-T6 alloy in 20% HNO3 + 0.1% NaCl has been studied. Weight loss measurements indicate that cerate or chromates generally suggested for chloride environments are rendered ineffective. H2SO4, though found to be the most efficient among the inhibitors examined (75% efficiency), does not provide adequate inhibition for safer inhibition. These inhibitors nevertheless provide good resistance against pitting corrosion. It is found that complete neutralization will reduce the corrosion of Al- alloy to a tolerable level. In this case cerium provides the best efficiency.
