Abstract

A method of reducing the nonuniformity of a galvanic coating on the basis of disableable anode sections in the inverse current reversal regime was proposed in a relatively simple technical implementation, thus providing the possibility to broaden the variety of articles treated for mass production. The galvanic process in the inverse current reversal regime with disableable anode sections was formalized by the formulation of an optimal control problem and the development of a mathematical model. Some results of computer-aided modeling were presented alongside with the results of verifying the developed mathematical model for adequacy with the use of experimental data to demonstrate the efficiency of the method proposed.
