The plating are widely spread in modern industry. To estimate its quality the proportionality is used as an index. Ordinary the proportionality depends on the grade of the barrel load, specifications of the barrels - construction and also on electrolytes - parameters and the parameters of plating. While using the plating, it-s possible to manage proportionality with the help of the current. Being in the barrel there are some spaces between the parts. In fact, the details present itselves porous electrode. The current is concentrated in the exteriors part of the work load, practically without permeation inside. For mathematical modeling of the plating is used the following approach. The starting work load which has a complex form in its cutting up is changed by the equivalent work load which has a round form in its cutting up. It-s suggested the mathematical model which permits to estimate the depth of currents - permeation in the work load. Also it-s suggested the mathematical model, which permits to estimate the current distribution , and therefore the proportionality.
