Nicotinic Acid as an Inhibitor of Corrosion of Pure Aluminium in Hydrochloric Acid Solutions

Abstract

Nicotinic acid has been found to be a fairly satisfactory inhibitor for the corrosion of pure aluminium in hydrochloric acid solutions, the efficiency being in the 59 to 98% range. Anode polarisation is low, whereas the cathode polarisation is considerable. The corrosion process seems to be essentially under cathodic control.
