Abstract

Frequency dependences of Fe films (SAS·HCl) at different times of their formation t (days): 1 – 1 day, 2 – 3 days, 3 – 5 days. Pressure P=104Pa.The corrosion behaviour of nickel in sulfuric acid in the presence of a benzimidazole derivative and its analogues with chloride anions has been studied. The investigated compounds are anodic type inhibitors that inhibit nickel corrosion by a blocking-energy mechanism. The extreme dependence of the protection degree of the obtained films on the content of chlorine anions in the inhibitor was interpreted on the basis of the competitive adsorption of the inhibitory and activating components of the inhibitor. As the inhibitor adsorption time increases, the degree of protection and physical characteristics (conductivity, electrical capacity) of the films on the Ni surface, in contrast to Fe, decrease monotonically. A microscopic analysis of the surface areas has shown that the organic films on Fe are characterized by a cellular structure, while in the films on Ni, a stripe-acicular structure in the shape of a “herringbone” is locally observed. The character of the current-voltage characteristics (CVC) and the negativity of the electric capacitances of all the studied films indicate the presence of a hopping-type mechanism in their conductivity.
