Abstract
An experimental investigation of an electrochemical dissolution of steel 110G13L (steel of Hadfield) in NaNO3, Na2SO4, and NaCl aqueous solutions was carried out. It has been found that the electrochemical dissolution of steel 110G13L in NaNO3, Na2SO4 aqueous solutions occurs in the active state when φ = 4.5 V. Based on the results of the polarization analysis and determination of the steel 110G13L dissolution depth in each of these solutions, the rational electrolyte composition was chosen for ECJM. The technologic experiment has shown that an increase in the electrolyte feeding pressure up to two МPа leads to a machining depth increase up to 600 μm.
