FIELD: chemistry.
SUBSTANCE: invention relates to application of metal coatings, particularly nickel coatings, by chemical reduction from solutions and can be used in microelectronics, instrument making and other industries. Disclosed is use of 2-(9-(methoxycarbonyl)-1,6-dioxo-1,3,4,6,7,8-hexahydro-2H-pyrido[1,2-α]pyrazin-7-yl)acetic acid with concentration of 0.28-28 mg/l as an additive which increases corrosion resistance of nickel-phosphorus coatings.
EFFECT: increase in the nickel-phosphorus coatings corrosion resistance, expressed in the corrosion potential reduction to -0.526 V, corrosion current to 2.98×10-7 A/cm2 and maintaining higher values of charge transfer resistance of coatings after 30 hours of testing compared to coatings obtained in absence of additives.
