The possibility of theoretical prediction of a given phase composition (intermetallide Ni 5 Zn 21 ) of Zn-Ni-Co electrochemical alloys using four phase formation criteria: entropy (n s ), dimensional (n d ), energy (n o ) and general (n º ) is shown. A theoretical method is proposed, which allows to predict the ratio of metal ions in solution and the phase composition of ternary electrolytic alloys, using Zn-Ni-Co alloy containing intermetallides as an example. Formation conditions (chemical content of the components in the coating) and the length of concentration boundaries of the metal-solvent (Zn) for electronic compound Ni 5 Zn 21 (γ phase) are calculated.
