Abstract

The inhibition effect of propargyl alcohol on the acidic corrosion of mild steel in 5 per cent commercial hydrochloric acid was studied at different temperatures by mass loss measurements and polarization studies. Corrosion potential and corrosion current have been calculated in the presence and in the absence of inhibitor. The inhibitor efficiency increases with increase in concentration and it decreases with rise in temperature. The interrelationship between the surface coverage and concentration of the inhibitor was also studied. It has been found that the inhibitor obeys Temkin adsorption isotherm.
