The optimal parameters for obtaining organic coatingsCoating with maximum protective effect, which correspond to a more perfect cellular microstructure of the organic filmOrganic film, have been established. A mixed blocking-energetic mechanism of inhibition with the prevailing influence of the structure of the electric double layer on the magnitude of the protective effect was determined. The heterogeneity of the steel surface in acid with an exponential distribution of adsorptionAdsorption centers of crystallization of the additiveAdditive was established.
