Description
Изобретение относитс к способам электролитического осаждени металлов и сплавов.The invention relates to methods for the electrolytic deposition of metals and alloys.
Известен способ электроосажденн сплава медь-цинк в пирофосфатном электролите, содержащем в качестве комплексообразовагел пирофосфат натри . Однако в этом электролнте не удаетс получить блест щие осадки снлава.A known method of electrodeposited copper-zinc alloy in a pyrophosphate electrolyte containing sodium pyrophosphate as a complexing agent. However, in this electrolytic process, it is not possible to obtain brilliant precipitate deposits.
Предлагаемый способ позвол ет получить блест щие осадки латупи, увеличить рассеивающую способность и yv yчщить стабильность электролита.The proposed method allows one to obtain brilliant precipitation of latupi, to increase the scattering power and yv to improve the stability of the electrolyte.
Дл этого в качестве пирофосфата щелочпоГо Металла в растворе используют пирофосфат кали , и в электролит дополнительно ввод т второй комплексообразоватсль - сульфосалнциловокислый натрий.For this, potassium pyrophosphate is used as the alkali metal pyrophosphate in solution, and the second complexing agent, sodium sulfosylcyl silicate, is added to the electrolyte.
Дл осаждени желтой латуни с содержанием 67-72% меди нроцесс ведут в электролите , содержащем, г/л:To precipitate yellow brass containing 67–72% copper, the process is carried out in an electrolyte containing, g / l:
Пинк сернокислый55-60Pink sulphate 55-60
Л1едь сернокисла 5-10L1e of sulfuric acid 5-10
Пирофосфат кали 240-250Potassium pyrophosphate 240-250
Сульфосалициловый патрий28-33Sulfosalicylic Patria28-33
Процесс ведут при рН 8,9-9,2, температуре 18-25°С и плотности..тока 0,5-1 ajOM (оптимально 0,6-0,7 а1дм-2).The process is carried out at a pH of 8.9-9.2, a temperature of 18-25 ° C and a density ... current of 0.5-1 ajOM (optimally 0.6-0.7 a1 dm-2).
Осадки латуии блест щие, обладают нрочиым сцеплением со сталью, Скорость осаждеКИЯ сплава 5-7 мк в час, аноды - лагунь Л-68 или Л-70.The sediments of lathium are shiny, have a weak adhesion to steel, the deposition rate of the alloy is 5-7 microns per hour, the anodes are Lagun L-68 or L-70.
Дл получени блест щих осадков сплава тина «Томпак (90-92% меди) в указанном электролите следует увеличить содержание меди до 8-10 г/л.In order to obtain brilliant precipitates of the Tompac alloy (90-92% copper) in this electrolyte, the copper content should be increased to 8-10 g / l.
Все комноненты раствор ют в отдельных порци х воды. Раствор сульфата цинка нриливают к раствору пирофосфата кали . Выпадающий вначале осадок пирофосфага цнпка All components are dissolved in separate portions of water. A solution of zinc sulfate is poured to a solution of potassium pyrophosphate. First precipitate of pyrophosphamic cyanogen

Зате .м раствор сульфосалицилата меди прили5 вают к раствору пнрофосфатпого комплекта цинка. По вл ющийс беловатый осадок легко раствор етс при неремещивании.0 dissolves easily when moved. The copper sulfate solution is added to the sodium sulfosalicylate solution. The color of the solution varies from blue to green. Then, a solution of copper sulfosalicylate is added to a solution of a monophosphate set of zinc. The whitish precipitate that appears easily dissolves when it is not displaced.
Полученный электролит соверщенпо нрозрачен и имеет синюю окраску. Он не требует The electrolyte obtained is perfect transparent and has a blue color. He does not require
