And inhibitory mechanism was analyzed by polarization curve and EIS. Kramers-Kronig transforms have been developed to apply the in the analysis of experimental electrochemical impedance data. XRD and EDS were carried out to examine corrosion products formed on the surface and adsorbed inhibitor. The results showed that compound inhibitor was mixed-type inhibitor and the inhibition efficiency was above 80% at 80℃. The impedance data do not satisfy Kramers-Kronig transforms. Corrosion product was mainly Fe3O4, content of elements in inhibitors filmed on electrode surface increased with concentration of inhibitors.
