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 was investigated with potentiodynamic current–potential curves from 298–343 K. For the same inhibitor concentration, a rise in temperature causes a positive shift in the corrosion potentials and an increase in the corrosion rates. The values of the activation energy Ea. determined here indicate that the inhibiting effect increases with inhibitor concentration. It is shown that adsorption is inconsistent with the Temkin isotherm. q1999 Published by Elsevier Science B.V. All rights reserved.
