Abstract

FIELD: electrolytic processes. SUBSTANCE: plating of copper from electrolyte on nickel and titanium-containing wire surface in the process of galvanic copper coating is carried out with varying cathode current density: 2-5 A/sq. dm until coating thickness attains 0.05-0.25 mcm in the beginning of process and 5.5-11 A/sq.dm until coating thickness attains 0.5-0.8 mcm. EFFECT: increased strength of coating.

Изобретение относится к гальваностегии, в частности к электролитическому меднению. Цель: обеспечение высоких прочностных качеств покрытия никель и титаносодержащей проволоки. Сущность изобретения: осаждение меди из электролита на поверхность проволоки в процессе гальванического меднения ведут с изменяющейся катодной плотностью тока, с величиной 2 - 5 А/дм2 до достижения толщины покрытия 0,05 - 0,15 мкм в начале процесса и величиной 5,5 - 11 А/дм2 до достижения толщины покрытия 0,5 - 0,8 мкм.The invention relates to electroplating, in particular to electrolytic copper plating. Purpose: ensuring high strength properties of the coating of nickel and titanium-containing wire. The inventive deposition of copper from an electrolyte on the surface of the wire in the process of galvanic copper plating is carried out with a varying cathode current density, with a value of 2 - 5 A / dm 2 to achieve a coating thickness of 0.05 - 0.15 μm at the beginning of the process and a value of 5.5 - 11 A / dm 2 to achieve a coating thickness of 0.5 - 0.8 microns.
