Description
1 ,one ,
Изобретение относитс к области получени электролитических сплавов.This invention relates to the field of producing electrolytic alloys.
Известен способ электролитического осаждени сплава олово-никель .в электролите, содержащем соли «икел , олова и пирофосфаг кали . Однако такой способ не обеспечивает получени качественных покрытий, а используемый раствор очень неустойчив в работе.The known method of electrolytic precipitation of tin-nickel alloy in an electrolyte containing ikel, tin and potassium pyrophosphate salts. However, this method does not provide high-quality coatings, and the solution used is very unstable in operation.
Предлагаемый способ отличаетс от известного тем, что в электролит ввод т этилендиамин И гидразин сол нокислый при следующем соотношении компонентов (в ): хлористый никель60-72The proposed method differs from the known one in that ethylenediamine I is hydrolyzed with hydrochloride in the following ratio of components (c): nickel chloride 60-72
хлористое олово20-25tin chloride20-25
пирюфосфат кали 300-350potassium pyrophosphate 300-350
этилендиамнн (20%-ный водный раствор)15-20 мл1лethylenediamine (20% aqueous solution) 15-20 ml1l
гидразин сол нокислый 4,,0 и процесс ведут лри плотности тока 0,25- 2,0 а/(лг2, рН 8,2-9,5 и температуре 50-60°С.Hydrazine 4, 4, 0, and the process is conducted at a current density of 0.25-2.0 a / (lg2, pH 8.2-9.5 and temperature 50-60 ° С.
Это позвол ет получать Мелкокристаллические светлые блест щие покрыти , а также повысить стабильность раствора.This allows to obtain fine crystalline bright shiny coatings, as well as to increase the stability of the solution.
При осуществлении описываемого способа используют олов нные аноды. Выход сплава по току 83-95%, содержание никел в сплаве .колеблетс от 20 до 40%.In the implementation of the described method using tin anodes. The current output of the alloy is 83-95%, the nickel content in the alloy is from 80 to 40%.
50°С с .последующим добавлением к раствору хлористого олова, а зате.м приготовленного отдельно раствора хлористого никел небольшими порци ми при интенсивном перемещиваНИИ . Этилендиамин и гидразин сол нокислый ввод т в .нагретый до 50°С раствор, после чего корректируют рН раствора добавлением аммиака или фосфорной кислоты, раствор отфильтровывают , охлаждают и довод т до требуемого объема.50 ° C with the subsequent addition of tin chloride to the solution, and then prepared separately for the nickel chloride solution in small portions with intensive displacement. Ethylenediamine and hydrazine hydrochloride are introduced into a solution heated to 50 ° C, then the pH of the solution is adjusted by the addition of ammonia or phosphoric acid, the solution is filtered, cooled and brought to the required volume.
