Abstract An attempt was made to inhibit cathodic corrosion of aluminium by the use of organic acids and bases. The corrosion is assumed to be caused by the effect of OH− ions formed from water upon cathodic hydrogen evolution. This is known to result in hydration of the protective oxide film and chemical attack on the metal. Hence, organic substances were expected to inhibit the corrosion by consuming OH− ions as well as by an adsorptive effect. The substances tested were HAc, HPro, HBut, HNic, TEA, Pyr, 3-Pic, 4-Pic, 3,5 Lut, 2,6 Lut, 2,4,6 Col, 4- HP, 2,4 AMP, 6,2 AMP, 2 AP and 3 AP. The best effect was achieved by TEA, 2,4 AMP and 2 AP, the potential window for low corrosion rate being extended by several hundred millivolts.
