摘要

The inhibitoryInhibitor effect of an organicOrganic compound of the imidazole class on the corrosion of low-carbon steel in sulfuric acid medium has been studied. The extreme dependence of the protective effect of the inhibitor on the time ofOrganic film organic film formation with a maximum at t = 2, 3 days was established. The adsorptionAdsorption mechanism of the additiveAdditive action was determined. Information on the surface morphologySurface morphology of the studiedOrganic film organic films depending on the time of their formation was obtained. The frequency dependencies of the electrical capacitance and theVolt-ampere characteristic (VAC) volt-ampere characteristics of the filmsFilm have been investigated.
