Dependence of the film active resistance on the uniaxial pressure Р. СSAS·HBr=3·10-3 mol/l in the mixed SAS·HBr+KBr inhibitor. The adsorption time is 3 days. f=1 kHz.

The inhibitory effect of a composite inhibitor based on an organic compound of the imidazole class and an inorganic salt in the corrosion of mild steel in sulfuric acid was studied. The analogy of protective properties of the combined inhibitor with protective properties of individual organic compounds was carried out. The mechanism of the protective action of the combined inhibitor was established. The threshold values of the concentration and adsorption time of the inhibitor have been determined, upon reaching which its maximum protective effect is realized, which corresponds to a more perfect cellular microstructure of the film surface. The electrical conductivity of the films is proportional to the inhibitor concentration and depends on the adsorption time. The calculated values of specific electrical conductivity of the coatings allow classifying them as organic semiconductors. Peculiarities of volt-ampere characteristics (VAC) characteristics of the films indicate the hopping mechanism of their conductivity.
