FIELD: metallurgy.
SUBSTANCE: invention refers to electrolytic metallurgy and can be used for copper coating on items of various purposes. Electrolyte contains copper (II) from 0.05 to 1.0 moles/l, nitriloti(methylenphosphonic) acid or its soluble compound from 0.1 to 2.0 moles/l, a substance of amines class chosen from the group consisting of monoethanolamine, diethanolamine, triethanolamine, N,N-dimethylethanolamine, ethylendiamine, diethylentriamine, triethylene-tetramine from 0.01 to 0.2 moles/l and water to 1.0 l.
EFFECT: producing of fine crystalline coating of high quality and performing of electrolyte in wide range of temperatures and pH values; also expanding range of complex phosphonic electrolytes for copper coating.
