ABSTRACT
The paper presents the results from a study of the possibility to use citric acid as an ecological inhibitor of corrosion in aluminum alloy EN AW-2024 in 0.5 М solution of H2SO4. The study has been carried out by using electrochemical techniques such as open circuit potential and chronoamperometry. The results reveal that the presence of citric acid in the studied acid medium reduces the degree of corrosion of the aluminum alloy EN AW-2024. The inhibition efficiency increases together with increasing the concentration of the citric acid. The study shows that the citric acid can be used as an ecological inhibitor to fight corrosion in a solution of H2SO4.
