SUMMARY
Paper discusses in details the notion of macrolevelling of current distribution and of coating thickness (throwing power of plating bath) in the cathodic deposition of metals and metal alloys. This notion is strictly related with metal distribution at the cathode and essentially depends on the cathodic current efficiency and on the polarization ratio in function of cathodic current density. Types of current distribution on details are given: of primary and secondary kinds. The methods of calculating of this distribution are given. They are based on Laplace’s equation solutions for adequate border conditions.
