FIELD: electroplating.
SUBSTANCE: invention relates to electroplating and can be used for electrodeposition of lustrous nickel coatings, particularly for protective and decorative finishing of parts in various industries. Electrolyte contains, g/l: nickel chloride hexahydrate (NiCl2⋅6H2O) 150–250; ammonium chloride (NH4Cl) 15–25; nickel sulphate heptahydrate (NiSO4⋅7H2O) 10–25; boric acid (H3BO3) 25–35, 2,5-diformylfuran (C6H4O3) 0.5–1.5.
EFFECT: increase of such process parameters of electrolyte as current efficiency and dissipation capacity, and coating properties – increase in lustre (reflectivity), microhardness, corrosion resistance and reduction of internal stresses of the nickel galvanic coating.
