Aluminum alloys are less corrosion resistance compared to the pure aluminum. The less corrosion resistance of the aluminum alloys results from trading their mechanical strength and stability with their corrosion resistance. Aluminum alloys show inhibition in alkaline, acidic, neutral chloride free, and chloride media. This study covers studies done on different inhibitors used in corrosion inhibition of aluminum alloys in various media. Generally, the inhibition efficiency of the inhibitors increases with increase in the concentration of the inhibitors. The inhibition efficiency also depends on the characteristic of the inhibitor; whether it is a mixed-type, anodic, or cathodic inhibitor. The experimental data fit in Langmuir adsorption isotherm indicates physical adsorption, while Gibb’s free energy values show that aluminum alloys’ corrosion inhibition is by spontaneous adsorption process. The addition of chloride in alkaline solution improves corrosion inhibition of aluminum alloys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
