The inhibition effect of hexamethylenetetramine on mild steel corrosion in hydrochloric acid solutions has been examined by means of an electrochemical polarization measurement and the surface observation of corroded specimens. The magnitude of corrosion current density was considerably large in 5 v/o HCI solution without inhibitor, i.e., 1.15x10-3 A/cm2 , but it was reduced effectively to 1.45x10- 4 A/cm2 even in the inhibitor concentration of 10 ppm. It can be concluded that the charge transfer reaction, i.e., Fe→Fe2+ + 2e and H+ + e→H are inhibited simultaneously and individually by the organic adsorption film at the metal/solution interface and consequently the corrosion-rate of the steel is reduced effectively in HCI solution.
