Modeling of the electrode polarization process in monitoring and controlling the process of applying galvanic coating

The mathematical model of the process of deposition of galvanic coating is considered, the distinctive feature of which is the consideration of concentration polarization. The results of studies of the relationship between the polarization of the electrodes, the uniformity of the coating distribution and the process parameters, such as the current density, the distance between the electrodes, the flow rate and the temperature of the electrolyte are presented. The hypothesis of the relationship between the uniformity of the coating and the cathode polarization is confirmed. It is established that the best distribution of the coating is ensured at higher values of electrode polarization.
