Effect of Heteronuclear Salicylate Complex {[FeSr2(SalH)2(Sal)2(NO3)(DMA)4]}n on Corrosion of Steel St. 3 in Water
The corrosion process of steel St. 3 in water with the addition of a heteronuclear salicylate complex {[FeSr2(SalH)2(Sal)2(NO3)(DMA)4]}n by gravimetric, electrochemical, and physicochemical methods (X‑ray phase analysis, UV, IR and Mössbauer spectroscopy) has been studied. It has been shown that the introduction of the additive under study into a corrosive environment significantly reduces steel corrosion. Depending on the duration of the tests and the concentration of the inhibitor, the corrosion rate is reduced by 5.1–11.1 times with a degree of protection of 80.5–91.0%. A mechanism of inhibition has been proposed. The inclusion of products of interaction of ionized iron with the complex in the coating layers has been proven.
