Description
Изобретение относитс к способам электролитического осаждени металлов.This invention relates to methods for the electrolytic deposition of metals.
Известен способ электроосаждени кадми в электролите, содержащем сернокислые соли кадми и аммони , борную кислоту и поверхностно-активное вещество, например клей, желатину и т. д.There is a known method of cadmium electrodeposition in an electrolyte containing cadmium and ammonium sulphate salts, boric acid and a surfactant such as glue, gelatin, etc.
Однако этот способ не позвол ет получать мелкокристаллические осадки больших толщин . Кроме того, используемый электролит обладает низкой рассеивающей способностью.However, this method does not allow to obtain crystalline precipitates of large thickness. In addition, the electrolyte used has a low scattering power.
С целью получени мелкокристаллических осадков и повышени рассеивающей способности электролита по предлагаемому способу Электролитического кадмировани в электролит ввод т синтанол ДС-10, и процесс ведут при рН 2-3, плотности тока 0,3-1,3 а/дм и температуре 18-25°С-.In order to obtain fine crystalline precipitates and increase the scattering ability of the electrolyte according to the proposed Electrolytic cadmium plating method, DS-10 synthanol is introduced into the electrolyte, and the process is carried out at pH 2-3, current density 0.3-1.3 a / dm and temperature 18-25 ° C-.
Примен предлагаемый способ, получать на стали и медных сплавах светлые мелкокристаллические и полублест щие покрыти , хорошо сцепленные с основой до толщин 30 .ПК и практически беспористые при толщине свыше 5 мк. Используемый электролит обладает хорошей рассеивающей снособностью .By applying the proposed method, to obtain on steel and copper alloys light crystalline and semi-glossy coatings, well adhered to the substrate to thicknesses of 30 pcs. And practically porous with thicknesses above 5 microns. The electrolyte used has a good dispersing ability.
Предлагаемый способ заключаетс в том, что процесс ведут в электролите, содержащем, моль/л:The proposed method consists in that the process is carried out in an electrolyte containing, mol / l:

Выход металла по току составл ет 85- 95%. Электролит устойчив в работе, корректировка по добавке производитс после нропускани через электролит 85 а-час/л.The current output of the metal is 85-95%. The electrolyte is stable in operation, the adjustment for the additive is made after dropping 85 a-h / l electrolyte through the electrolyte.
Вводимое в электролит поверхностно-активное вещество неноногенного типа синтанол ДС-10 представл ет собой оксиэтилированный синтет11ческий спирт.The non-nongenic type surfactant DC-10 introduced into the electrolyte is ethoxylated synthetic alcohol.
