Description
Известные способы электролитического отложени висмута базируютс на кислых электролитах (азотнокислые, сол нокислые, хлорнокислые и т. д.).The known methods of electrolytic deposition of bismuth are based on acidic electrolytes (nitric acid, hydrochloric acid, perchloric acid, etc.).
Новый способ электролитическото отложени висмута базируетс на щелочных растворах.A new method of electrolytic deposition of bismuth is based on alkaline solutions.
Дл гальванического висмутировани предлагаютс два щелочных электролита, содержащие в качестве комплексообразовател трилон Б. Один из них - дл висмутировани только меди и ее сплавов - работает лри ПЛОТНОСТИ тока 0,2-0,6 a/dw, второй - дл висмутировани не только медных, но и стальных изделий - работает при плотности тока 0,2-0,3 а1дм.Two alkaline electrolytes are proposed for electroplating bismuth containing Trilon B as a complexing agent. One of them — for the bismuthization of copper and its alloys — works with a current density of 0.2–0.6 a / dw; but also steel products - it works at a current density of 0.2-0.3 a1 dm.
Дл приготовлени электролита висмутировани меди и ее сплавов к водному раствору трилона Б при нагревании добавл ют вначале необходимое количество висмутата натри ; раствор хорошо размещин ают и добиваютс возможно более полного растворени висмутата. Оставщийс осадок висмутата полностью раствор ют при добавлении сегнетовой соли. После этого к холодному электролиту добавл ют при размещивании щелочь. Стол рный клей намачивают в отдельной порции воды, а затем немного нагревают. После остывани клей добавл ют ко всему электролиту. Хорошо приготовленный электролит должен иметь светложелтый цвет.In order to prepare the electrolyte of copper bismuth and its alloys, the required amount of sodium bismuthate is first added to the aqueous solution of Trilon B by heating; the solution is well placed and achieve the fullest possible dissolution of bismuthate. The remaining bismuthate precipitate is completely dissolved by the addition of the Rochelle salt. Thereafter, alkali is added to the cold electrolyte while placing. Stub glue is soaked in a separate portion of water, and then slightly heated. After cooling, the glue is added to the entire electrolyte. A well-prepared electrolyte should have a light yellow color.
Дл висмутировани меди и ее спланов используют следующий состав электролита (в г/л):The following electrolyte composition (in g / l) is used for the bismulation of copper and its planes:
висмутат натри - 20sodium bismuth - 20
трилон Б-60Trilon B-60
сегнетова соль - 80segnetova salt - 80
едкий натр - 150caustic soda - 150
клей стол рный - 8glue table ryny - 8
Издели из меди и ее сплавов трав т в смеси концентрированных азотной и серной кислот (последн беретс в количестве 10 мл/л). После травлени издели тщательно промываютс проточной водой.Products made of copper and its alloys are etched in a mixture of concentrated nitric and sulfuric acids (the latter is taken in an amount of 10 ml / l). After pickling, the products are thoroughly rinsed with running water.
Висмутирование ведут при комнатной температуре, при непрерывном перемещивании. Плотность тока 0,2-0,6 а/дм. Аноды - висмутовые . Поверхность анодов равна поверхности катодов.Batching is carried out at room temperature, with continuous movement. Current density 0.2-0.6 a / dm. Anodes - bismuth. The surface of the anodes is equal to the surface of the cathodes.
