FIELD: galvanostegy. SUBSTANCE: electrolyte has, g/l: zinc sulfate 140-160; cobalt sulfate 15-30; ammonium sulfate 5-15; boric acid 10-30; nonionogenic surface-active substance 5-6, and organic addition 0.5-2.0. Organic addition is product of interaction of p-aminobenzoic acid with cinnamic aldehyde at their molar ratio = 1:1. Precipitation is carried out at current density range 0.5-4 A/dm2.. Cathode yield by current is 85-90%. Electrolyte ensures to obtain the homogeneous zinc-cobalt coatings containing 0.3-1.0% cobalt on rough adhesion surface. Invention can be used in radioelectronic, electric engineering, automobile and other branches of industry. EFFECT: enhanced quality of electrolyte. 2 tbl
