Description
Известен способ электроосаждени сплавов золота с металлами группы железа из цианистых растворов.The known method of electrodeposition of alloys of gold with metals of the iron group from cyanide solutions.
Дл улучшени качества покрыти предложено процесс электроосаждени вести при температуре 50°С, плотности тока 0,5-1 а1дм и рН 7 из электролита следующего состава, г/л:To improve the quality of the coating, an electrodeposition process has been proposed to be carried out at a temperature of 50 ° C, a current density of 0.5-1 a1 dm and a pH of 7 from an electrolyte of the following composition, g / l:
золото (в пересчете на металл)0,03-3gold (in terms of metal) 0.03-3
в виде цианистого соединени in the form of a cyanide compound
железо (в пересчете на металл)1-3iron (in terms of metal) 1-3
в виде виннокислого комплексаin the form of tart-acid complex
сегнетова соль150segnetov salt150
борна кислота20-30boric acid 20-30
Состав получаемого сплава регулируют изменением соотношени концентраций золота и железа в растворе и плотностью тока.The composition of the resulting alloy is controlled by changing the ratio of the concentrations of gold and iron in the solution and the current density.
Так, например, при содержании золота 2,6 и железа 1,0 г/л осаждают сплав с содержанием ЗО/о железа, а при содержании золота 0,3 г/л и железа 3 г/л содержание железа в сплаве возрастает до Эбо/оПредлагаемый способ позвол ет получать сплав с высокими физико-химическими свойствами и прочным сцеплением с основным металлом издели .For example, when the gold content is 2.6 and iron is 1.0 g / l, the alloy is precipitated with an iron / iron content of 3/3, and when the gold content is 0.3 g / l and iron is 3 g / l, the iron content in the alloy increases to The proposed method allows to obtain an alloy with high physicochemical properties and strong adhesion to the base metal of the product.
