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.

коструйную обработку, и детали, после цинкатной обработки и травлени  в азотной кислоте, серебр т контактно в растворе следующего состава (в серебро (в пересчете на металлическое) 3-6, калий цианистый 70-100, после чего без промывки перенос т в электролит дл  электроосаждени  серебра.kostruynuyu processing, and details, after zincate treatment and etching in nitric acid, silver contact in a solution of the following composition (in silver (based on metallic) 3-6, potassium cyanide 70-100, then without washing is transferred into the electrolyte for silver deposition.
