This article presents the results of experimental studies to determine the relationship between electrolysis modes and the properties of electroplated coatings, which are used in mathematical modeling of the dynamics of the electrolytic process, described by a system of ordinary differential equations due to the complex relationship between the kinetics of chemical reactions, hydrodynamics and mass transfer in the electrolyte stream, the kinematics of electrode plates, as well as the influence on all these processes of the electric field of the pair “anode-cathode”. At the same time, a series of field experiments to restore the seats of the main bearings of the cylinder blocks with galvanic coatings served as the experimental base. The final result of this study is the procedure for constructing an optimal resource-saving mode of deposition of galvanic coatings, which are a zinc-iron alloy.
