Description
Серебрению алюминиевых сплавов известными способами предшествуют подготовительные операции: пескоструйна обработка поверхности детали и электроосаждение на очищенную поверхность меди или никел (в качестве подсло под серебро).Silver alloys of aluminum alloys are preceded by preparatory operations by known methods: sandblasting the surface of the part and electroplating copper or nickel onto the cleaned surface (as a sublayer for silver).
Предлагаетс из процесса эти операции исключить.It is proposed to exclude these operations from the process.
Сущность предлагаемого способа. Детали сложного профил после цинкатной обработки и травлени в азотной кислоте подвергают контактному серебрению в растворе, содержащем 3-6 г/л серебра (в пересчете на металлическое) и 70-100 г/л цианистого кали . Обработанные таким образом детали без промывки перенос т в цианистый электролит обычного состава дл последующего электролитического серебрени . В результате получают равномерное покрытие при прочном сцеплении серебра с основой.The essence of the proposed method. Details of the complex profile after zinc processing and etching in nitric acid are subjected to contact silvering in a solution containing 3-6 g / l of silver (based on metallic) and 70-100 g / l of potassium cyanide. The parts thus treated without rinsing are transferred to a cyanide electrolyte of conventional composition for subsequent electrolytic silvering. The result is a uniform coating with strong adhesion of silver to the base.
Опытные образцы были успещно испытаны при изгибе, ударе, нагреве и охлаждении до 60°С,Prototypes were well tested in bending, impact, heating and cooling to 60 ° C,
Предмет изобретени Subject invention
Способ электролитического серебрени деталей сложного профил из-алюмини и егосплавов, отличающийс тем, что, с целью получени равномерного покрыти и прочного сцеплени серебра с основой , из процесса подготовки алюмини к серебрению исключают пес№ 145101The method of electrolytic silvering of parts of a complex profile made of aluminum and alloy, characterized in that, in order to obtain a uniform coating and strong adhesion of silver to the base, the number 145101 is excluded from the process of preparing aluminum for silvering.
