The influence of a corrosive medium on the transformation of strength properties of a steel 45 surface layer subjected to impact electromechanical treatment is studied. Results are provided for a study of the effect of impact electromechanical treatment regimes on the corrosion activity of strengthened specimens, estimated by the change in hardened surface layer microhardness. The nature and degree of reduction in strengthened surface layer hardness in specimens strengthened with current density j = 100, 300, and 600 A/mm 2 are established in relation to corrosion test duration.
