Description
Известные электролиты дл меднени стальных изделий содержат довитые цианистые соединени .Known electrolytes for the copper plating of steel products contain poisonous cyanide compounds.
Дл устранени этого недостатка нредлагаетс электролит, в состав которого не вход т вредные цианистые соединени . Состав электролита характеризуетс следующим соотношением компонентов 15 г/л углекислой меди, 40 г/л сернокислого натри и 30 г1л этилендиаминотетрауксусНокислого натри .To eliminate this drawback, an electrolyte is proposed which does not contain harmful cyanide compounds. The composition of the electrolyte is characterized by the following ratio of components: 15 g / l of copper carbonate, 40 g / l of sodium sulfate and 30 g of ethylene diamine tetra-acetic acid sodium.
Благодар нрименению электролита предлагаемого состава улучшаютс услови труда. При этом медные осадки получаютс беспористыми , мелкокристаллическими и плотными и хорошо сцепл ютс с основой.Due to the use of the electrolyte of the proposed composition, the working conditions are improved. Copper deposits are thus obtained that are non-porous, fine crystalline and dense and adhere well to the substrate.
Электролит может примен тьс дл меднени стальных и железных деталей, с целью избирательной защиты их поверхности в процессе цементации , или как подслой при нанесении декоративных многослойных покрытий.The electrolyte can be used for copper plating of steel and iron parts, in order to selectively protect their surface during the cementation process, or as a sublayer when applying decorative multilayer coatings.
