• The effect of benzaldehyde, 2-hydroxybenzoyl hydrazone derivatives on the corrosion of aluminium in hydrochloric acid has been investigated using themometric and polarization techniques. The inhibitive efficiency ranking of these compounds from both techniques was found to be : 2>3>1>4. The inhibitors acted as mixed-type inhibitors but the cathode is more polarized. The relative inhititive efficiency of these compounds has been explained on the basis of structure of the inhibitors and their mode of interaction at the surface. Results show that these additive are adsorbed on an aluminium surface according to the Langmuir isotherm. Polarization measurements indicated that the rate of corrosion of aluminium rapidly increases with temperature over the range 30-55℃ both in the absence and in the presence of inhibitors. Some thermodynamic data of the adsorption process are calculated and discussed.
