Abstract
Possibilities of the anodic oxidation of the medium-carbon steel by electrothermochemical treatment in 10–15 % aqueous ammonium acetate solution is shown. Tests of oxidation specimens in the 0.5M H2SO4 solution is shown, that anodic potential of the oxidation specimens is shifted to positive values (0.3 V), their conductivity is lowed. Minimum corrosion rate [0.7 g/(m2⋅day)] in the 5 % NaCl solution was obtained for specimen that was oxidize at the voltage 200 V.
