Description
Известны способы подготовки алюминиевых изделий дл гальванических покрытий путем обработки их в подкисленных растворах солей т желых металлов, например хлорного железа, хлористого никел , двуххлористой меди. Однако эти способы не дают качественных результатов , так как в процессе травлени алюмини в растворах образующа с на нем пленка выделенного металла слабо сцепл етс с основным металлом.Methods are known for the preparation of aluminum products for electroplating by treating them in acidified solutions of heavy metal salts, such as ferric chloride, nickel chloride, and copper chloride. However, these methods do not give qualitative results, since in the process of aluminum etching in solutions, the film of the selected metal formed on it weakly adheres to the base metal.
Известен также способ обработки алюмини в растворе цинката натри с последующим никелированием в растворе, содержащем лимонную кислоту. Но дл обеспечени проч,ного сцеплени необходима последующа термообработка.There is also known a method of treating aluminum in a solution of sodium zincate, followed by nickel plating in a solution containing citric acid. But to ensure a strong adhesion, subsequent heat treatment is necessary.
Предлагаемый способ позвол ет получить прочное сцепление покрыти с алюминием. Дл этого обезжиренные и протравленные в растворе едкого натра издели из м гкого алюмини обрабатывают в растворе, содержащем 1 л фосфорной кислоты (уд. в. 1,4) и 40 л хлористого никел при температуре 50-60°. Врем обработки составл ет 0,5-2 мин до удалени естественной пленки. The proposed method allows a strong adhesion of the coating to aluminum. To do this, products of soft aluminum, degreased and pickled in a solution of caustic soda, are treated in a solution containing 1 liter of phosphoric acid (sp. In. 1.4) and 40 l of nickel chloride at a temperature of 50-60 °. The processing time is 0.5-2 minutes before the natural film is removed.
После промывки в проточной воде обработанна поверхность алюмини имеет светло-серый цвет. Подготовленные описанным способом детали подвергают далее гальваническому покрытию металлами при помощи известных методов.After washing in running water, the treated aluminum surface has a light gray color. Prepared as described in the details are then subjected to galvanic metal coating using known methods.

Способ подготовки алюминиевых изделий дл гальванических покрытий , отличающийс тем, что, с целью получени прочного сцеплени покрыти с алюминием, издели обрабатывают в растворефосфорна кислота (уд. в. 1,4) 1 л, никель хлористый 40 л, при температуре 50-60° в течение от 0,5 до 2 мин.The method of preparing aluminum products for electroplating, characterized in that, in order to obtain a strong adhesion of the coating to aluminum, the products are treated in phosphoric acid solution (sp. 1.4) 1 l, nickel chloride 40 l, at a temperature of 50-60 ° within 0.5 to 2 minutes
