Inhibition of thermogalvanic corrosion in sulfate media

The effect of traditional inhibitors of acid corrosion (urotropine, benzotr iazole, and thiocarbamide) on the corrosion-electrochemical behavior of an iron plate with a tangential thermal gradient in a sulfate-containing acid solution is examined. The inhibitors are shown to significantly weaken the thermogalvanic (TG) corrosion intensity, reducing the TG currents and total weight tosses of iron in the thermoelectric zone by factors of 1.3 to 2.0 and 1.1 to 1.4 times, respectively.
