Abstract: Traditional electrochemical testing technology and atomic force microscopy (AFM) force curve measurement were performed to research the adsorption behavior of corrosion inhibition film on dodecanethiol/gold electrode and sodiumdodecyl sulfate (SDS)/aluminumelectrode systems. The results showed that the corrosion inhibitor layer obtained at different concentrations presented different micro adhesive force characteristics, being associated with the changing regularity of the electrodes’ electrochemical behavior. The research demonstrated that AFM force curve technology was a successful way to investigate the adsorption behavior of corrosion inhibition film.

Key words: Corrosion inhibition film, Electrochemical behavior, AFM force curve, Adhesive force
