The effect of crotyl alcohol on the corrosion of austenitic chromium-nickel steel

In this study, the corrosion inhibition of austenitic chromium-nickel steel in an acidic medium containing Various concentrations of crotyl alcohol wa s investigated with potentiodynamic current-potential curves from 298-343 K . For the same inhibitor concentration, a rise in temperature causes a posi tive shift in the corrosion potentials and an increase in the corrosion rat es. The values of the activation energy (E-a) determined here indicate that the inhibiting effect increases with inhibitor concentration. It is shown that adsorption is inconsistent with the Temkin isotherm. (C) 1999 Publishe d by Elsevier Science B.V. All rights reserved.
