Description
Известны различные способы электроосаждеии серебра и его сплава из цианистых электролитов.There are various methods of electrodeposition of silver and its alloy of cyanide electrolytes.
Предлагаемый способ позвол ет повысить износостойкость, твердость и коррозионную стойкость осаждаемых покрытий и заключаетс в электрохимическом осаждении сплава серебро- кобальт из цианистопирофосфатного электролита.The proposed method allows to increase the wear resistance, hardness and corrosion resistance of the deposited coatings and consists in the electrochemical deposition of the silver-cobalt alloy from the cyanide pyrophosphate electrolyte.
Состав электролита следующий (в г/л); серебро (в пересчете на металл) 0,1-0,4 (добавл етс в виде цианистого соединени ); кобальт (в пересчете на металл) 2-3,2 (готовитс как пирофосфатный комплекс); пирофосфат кали (свободный) 100.The electrolyte composition is as follows (in g / l); silver (in terms of metal) 0.1-0.4 (added as a cyanide compound); cobalt (in terms of metal) 2-3.2 (prepared as a pyrophosphate complex); potassium pyrophosphate (free) 100.
Процесс ведут с перемешиванием электролита при температуре 40-45° С и плотности тока 0,1-0,5 аноды - нержавеюща сталь.The process is carried out with mixing of the electrolyte at a temperature of 40-45 ° C and a current density of 0.1-0.5 anodes - stainless steel.
При концентрации серебра 0,3 г/л и кобальта 3,2 г/л осаледаетс сплав с содержанием 4% кобальта, а при 0,1 г/л серебра и 2,1 г/лAt a concentration of silver of 0.3 g / l and cobalt of 3.2 g / l, the alloy containing 4% cobalt is deposited, and at 0.1 g / l of silver and 2.1 g / l
Кобальта содержание кобальта в сплаве воз растает до 87%.Cobalt cobalt content in the alloy increases to 87%.
Предлагаемый способ позвол ет получать сплав с высокими физико-механическими свойствами и прочным сцеплением с основным металлом издели .The proposed method allows to obtain an alloy with high physicomechanical properties and strong adhesion with the base metal of the product.
Предмет изобретени Subject invention
Электрохимический способ получени двойного сплава серебра из электролита, содержащего его цианистый комплекс, отличающийс тем, что, с целью повышени износостойкости, твердости и коррозионной стойкости осаждаемых покрытий, процесс ведут при температуре 40-45°С, плотности тока 0,1-0,5 а/дм-2 и перемешивании электролита, в состав которого ввод т пирофосфат кобальта и пирофосфат кали при следующем соотношении компонентов (в г/л):The electrochemical method of producing a double silver alloy from an electrolyte containing its cyanide complex, characterized in that, in order to increase the wear resistance, hardness and corrosion resistance of the deposited coatings, the process is carried out at a temperature of 40-45 ° C, a current density of 0.1-0.5 a / dm-2 and stirring of the electrolyte, which contains cobalt pyrophosphate and potassium pyrophosphate in the following ratio of components (in g / l):
Серебро (в пересчете на металл) 0,1-0,4 Кобальт (в пересчете на металл) 2-3,2 Пирофосфат кали (свободный)100Silver (in terms of metal) 0.1-0.4 Cobalt (in terms of metal) 2-3,2 Potassium pyrophosphate (free) 100
