Description
Известен способ получени дисперсных осадков сплавов палладий - медь путем совместного осаждени из растворов сернокислой меди и комплексной соли паллади . При этом ванны готов т, раствор в воде, подкисленной серной кислотой, рассчитанные количества солей PdCl3-2H2O, NANOg, CuS04-5H.20, (NH4) 280.1.A known method for producing dispersed precipitates of palladium-copper alloys by co-precipitating from solutions of copper sulphate and palladium complex salts. In this case, the baths are prepared, a solution in water, acidified with sulfuric acid, the calculated amounts of salts PdCl3-2H2O, NANOg, CuS04-5H.20, (NH4) 280.1.
Особенностью предлагаемого снособа вл етс осаждение сплавов палладнй - медь из электролитов, содержанднх медь в виде пирофосфатного, а палладий - в виде аммиачного комплекса, что позвол ет получить на катоде качестве1И1ые плотные компактные осадки.The peculiarity of the proposed removal method is the deposition of palladium alloys - copper from electrolytes, copper in the form of pyrophosphate, and palladium - in the form of ammonia complex, which allows to obtain as a dense compact precipitation at the cathode.
Сущность способа. Сплавы получают электролитическим осаждением из электролита.The essence of the method. Alloys are produced by electrolytic deposition from an electrolyte.
в которьп ввод т иалладий в виде аммиачного комплекса, а медь -- в впде иирофосфатного комплекса. Раствор содержит также добавки едкой щелочи дл предупреждени образовани рыхлого осадка и поддержани стабильности состава покрытий.Ialladium is introduced into the ammonia complex, and copper is introduced into the pyrophosphate complex. The solution also contains caustic additives to prevent the formation of loose sediment and maintain the stability of the coating composition.
Предмет изобретени Subject invention
