Description
ЭЛЕКТРОЛИФ ДЛЯ ОСАЖДЕНИЯ СПЛАВА МЕДЬ-ЦИНКELECTROLYPHE TO DEPOSIT THE COPPER-ZINC ALLOY
Изобретение относитс к технологии электроосаждени металлов и сплавов.The invention relates to the technology of metal deposition of metals and alloys.
Известен электролит дл получени сплава медь-цинк, содержащий серокислые соли меди , цинка и органический комплексообразователь , например, этаноламин.An electrolyte is known for producing a copper-zinc alloy containing copper sulfate, zinc sulfate salts and an organic complexing agent, for example, ethanolamine.
Однако такой электролит обладает низкой производительностью.However, this electrolyte has a low productivity.
С целью интенсификации процесса электроосаждени и получени осадков хоронтсго качества толщиной 50-100 мк при плотности тока 6-8 а/дм на непрерывно движущемс катоде предложенный электролит содержит сернокислый аммоний и в качестве органического комплексообразовател - полиэтиленполиамин при следующем содержании компонентов , г/л:In order to intensify the process of electrodeposition and obtain precipitates of bore quality 50-100 microns thick at a current density of 6-8 a / dm on the continuously moving cathode, the proposed electrolyte contains ammonium sulphate and, as an organic complexing agent, polyethylene polyamine with the following content of components, g / l:
сернокисла медь15-18sulfate copper15-18
сернокислый цинк75-80zinc sulphate75-80
сернокислый аммоний40-50ammonium sulphate40-50
полиэтиленполиамин100-120.polyethylenepolyamine100-120.
Процесс электроосал1дени ведут при рН 8-9, температуре 18-25°С и катодной плотности тока 6-8 а/дм.The process of electroalysis is carried out at a pH of 8–9, a temperature of 18–25 ° C, and a cathode current density of 6–8 A / dm.
При отношении Cu/Zn в электролите равном 1/5 сплав содерЛСИт 10-12% цинка.When the ratio of Cu / Zn in the electrolyte is equal to 1/5 alloy contains 10-12% zinc.
Анодный и катодный выходы по току в указанных услови х составл ют 85-90%.The anodic and cathodic current outputs under these conditions are 85-90%.
Дл приготовлени электролита вначале получают отдельно полиэтиленполиаминовые комплексы меди и цинка. Затем растворы смещивают и добавл ют раствор сернокислого аммони . Электролит довод т до расчетного объема ,и фильтруют.To prepare the electrolyte, first polyethylenepolyamine complexes of copper and zinc are prepared separately. The solutions are then shifted and a solution of ammonium sulphate is added. The electrolyte is adjusted to the calculated volume, and filtered.
Предмет изобретени Subject invention
