Аннотация:This work is devoted to the theoretical study of the effect of anode shape, insulating shields, the exchange
current density and operating conditions on the uniformity of metal layer deposited onto the resistive
cathode. Laplace’s equation for the potential in the electrolyte solution, Poisson’s equation for the
potential in the resistive cathode, and the equation of metal thickness evolution were used as the
mathematical model. The numerical solution was performed using the boundary element and
finite
element methods. The possibilities for controlling the distribution of deposit thickness over the cathode
surface are demonstrated by the example of metal deposition onto an annulus workpiece. The use of the
anode of the calculated shape enabled us to obtain a deposit of uniform thickness over almost the entire
workpiece surface except for the very edges, where the deposit was thicker. The application of shields
designed in the work enabled us to eliminate this drawback
