Description

Изобретение относитс  к области гальванических покрытий, в частности к электрохимическому осаждению сплава на основе серебра. Известен способ электрохимического осаждени  сплава на основе серебра из электролита , содержащего соль серебра, пирофосфорнокислый калий, цианистый калий. Однако по известному способу нельз  получить сплав серебро-олово . Цель изобретени  - получение износостойких и твердых осадков сплава серебро-олово . Это достигаетс  тем, что в электролит ввод т соль олова при следуюи1,ем соотношении компонентов (г/л): Серебро (на металл)10-20 Олово (на металл)20- 30 Пирофосфорнокислый калий ( свободный)170-220 Цианистый калий (свободный )2- 10 и процесс ведут при комнатной температуре, рН 8,7-9,2 и катодной плотности тока 0,5- 5 . По предложенному способу получают сплав серебро-олово с содержанием олова до 40 вес. %. Так, например, из электролита, содержащего (г1л): Серебро (на металл)20 Олово (на металл)20 Пирофосфорнокислый калий ( свободный)220 Цианистый калий (свободный )7,5 ри комнатной температуре, рН 8,7-9,2 и анодной нлотностн тока 0,1 a/d.M- осаждают сплав с 4-5% олова, который может быть нспользован дл  покрыти  электролитических контактов. Предмет изобретени  Способ элeктpoxиJMИчecкoгo осаждени  сплава на основе серебра из электролита, содержащего соль серебра, Пирофосфорнокислый калий, цианистый калий, отличающийс  тем, что, с целью получени  износостойких и твердых осадков сплава серебро-олово, в электролит ввод т соль олова при следующем соотнощении компонентов (г/л): Серебро (на металл)10-20 Олово (на металл)20- 30 Пирофосфорнокислый калий ( свободный)170-220 Цианистый калий (свободный ).2- 10 процесс ведут при комнатной температуре, рН 8,7-9,2 и катодной плотности тока 0,5- 5 .The invention relates to the field of electroplating, in particular to the electrochemical deposition of an alloy based on silver. The known method of electrochemical deposition of an alloy based on silver from an electrolyte containing silver salt, potassium pyrophosphate, potassium cyanide. However, by a known method it is impossible to obtain a silver-tin alloy. The purpose of the invention is to obtain wear-resistant and solid precipitates of silver-tin alloy. This is achieved by introducing the salt of tin into the electrolyte at the following1, it is the ratio of components (g / l): Silver (for metal) 10-20 Tin (for metal) 20-30 Potassium pyrophosphate (free) 170-220 free) 2-10 and the process is carried out at room temperature, pH 8.7-9.2 and a cathode current density of 0.5-5. According to the proposed method, an alloy of silver-tin with a tin content of up to 40 weight. % For example, from an electrolyte containing (r1l): Silver (for metal) 20 Tin (for metal) 20 Potassium pyrophosphate (free) 220 Potassium cyanide (free) 7.5 at room temperature, pH 8.7-9.2 and anodic current density of 0.1 a / dM- precipitated alloy with 4-5% tin, which can be used to coat electrolytic contacts. The subject of the invention is a method for the electrolytic and chemical deposition of a silver-based alloy from an electrolyte containing silver salt, potassium pyrophosphoric acid, potassium cyanide, characterized in that g / l): Silver (for metal) 10-20 Tin (for metal) 20-30 Potassium pyrophosphate (free) 170-220 Potassium cyanide (free) .2-10 process is carried out at room temperature, pH 8.7-9 , 2 and a cathode current density of 0.5 - 5.
