Изобретение относитс  к способам электроосаждени  сплавов цинка, в частности сплава цинк-фосфор.This invention relates to methods for the electroplating of zinc alloys, in particular a zinc-phosphorus alloy.

Известен способ злектроосаждени  сплавов цинка, например, сплава цинк-кадмий в электролите, содержагцем хлористые соли цинка , кадми , аммони  и полиэтнленполиамин.There is a known method for the precipitation of zinc alloys, for example, a zinc-cadmium alloy in an electrolyte containing chloride salts of zinc, cadmium, ammonium and poly ethylene polyamine.

Предложенный способ позвол ет получать электролитически качественные осадки сплава цинк-фосфор с содержанием фосфора в сплаве от 0,4 до 6%.The proposed method allows to obtain electrolytically high-quality precipitates of a zinc-phosphorus alloy with a phosphorus content in the alloy of 0.4 to 6%.

По предложенному способу покрытие сплавом цинк-фосфор получают из электролита, содержащего, г/л:According to the proposed method, the coating of zinc-phosphorus alloy is obtained from an electrolyte containing, g / l:

при плотности тока 0,6-9 а/сж температуре 20-бО С и рН 4,0-5,4.at a current density of 0.6-9 a / c, the temperature of the temperature is 20bC and pH 4.0-5.4.

Процесс ведут с анодами из платины.The process is conducted with anodes of platinum.

Пример. В электролите, содержащем 68 г/л цинка хлористого, 30 г/л гипофосфита натри  и 92 об. % водного раствора этанолаExample. In the electrolyte containing 68 g / l of zinc chloride, 30 g / l of sodium hypophosphite and 92 vol. % aqueous solution of ethanol

при плотности тока 2 а/дм, температуре 30°С и рН 5,1 получают покрыти  сплавом цинк-фосфор с содержанием фосфора 1,06%. В электролите аналогичного состава при плотности тока 1 а/дм и температуре 60°С получают покрытие сплавом цинк-фосфор с содержанием фосфора 0,4%. При этом выход сплава по току составл ет 95%.at a current density of 2 a / dm, a temperature of 30 ° C and a pH of 5.1, coatings are obtained with a zinc-phosphorus alloy with a phosphorus content of 1.06%. In the electrolyte of a similar composition at a current density of 1 A / dm and a temperature of 60 ° C, a zinc-phosphorus alloy coating with a phosphorus content of 0.4% is obtained. The current output of the alloy is 95%.
