Abstract

The inhibition of the corrosion of Al in hydrochloric acid solution by some Schiff bases has been studied in relation to the concentration of the inhibitor as well as the temperature. The inhibition efficiency increases with increasing inhibitor concentration. The inhibitors appear to function through the Langmuir isotherm. Polarisation studies indicate that the compounds used are cathodic inhibitors. The corrosion kinetics has also been studied.
