Corrosion Inhibitors for Aluminium Alloys

Abstract

Abstract Data (including literature data) are presented on the inhibition of the corrosion of Al and some Al alloys in hydrochloride, sulfuric, acetic and oxalic acids and sodium hydroxides. In this context the influence is shown of parameters such as inhibitors structure and concentration, temperature, time, medium concentration and external currents. Inhibitors dealt with include aliphatic and aromatic amines, carbonyl compounds (aldehydes, ketones); in this context it is shown that functional groups and their relative positions may have an important effect on inhibitor efficiencies.
