Özet

In this study, the corrosion inhibition of austenitic chromium-nickel steel in acidic medium containing various concentrations of N-(1-toluidine) salicylaldimine was investigated with the help of potentiodynamic current-potential curves in the temperature range of 298-338 K. It is seen that for the same inhibitor concentration, the rise in temperature causes positive shift in the corrosion potentials and increase in the corrosion rates. It was shown that adsorption is consistent with the Temkin isotherm for 298 K and the Frumkin isotherm for other temperatures. (C) 1999 Elsevier Science B.V. hll rights reserved.
