Anodic treatment of steel 40Kh in a 35-% sulfuric acid electrolyte containing chloride ions

  • Yu. A. Ivashkin
Short Communications


Anodic dissolution of steel 40Kh in a sulfuric acid electrolyte containing Cl ions is studied by analyzing the experimental dependence of anodic current on the specimen potential. The dependences of the critical passivation current, anodic current at −0.15 to 0.55 V (Ag/AgCl), and passivation current on the concentration of Cl ions (c) are determined. The maximum value of c for the passivation at 0.55–1.6 V (Ag/AgCl) is refined. The dependence of the specimen’s steady-state potential on c is determined and its decrease is related to an abrupt increase in the anodic current at the passivation potentials.
