Изобретение относитс к хими:ческой обработке металлов, в частности к растворам дл травлени магнитнопрецизионных никелевых сплавов и дл травлени стали, и может быть использовано в электронной промьшшенности, а также на автоматических лини : :.The invention relates to the chemical treatment of metals, in particular, solutions for the etching of magnetically precision nickel alloys and for the etching of steel, and can be used in electronic industry, as well as on automatic lines:.
Цель, изобретени - повьшение качества поверхности.The goal of the invention is to increase the quality of the surface.
Результаты обработки поверхности сплава 79 НМ в различных; растворах травлени приведены в таблице.The results of surface treatment of 79 NM alloy in various; etching solutions are given in the table.
Из таблицы следует, что только совместное содержание в растворе хлорного железа, аммони лимонно-кйслого и натри или кали серно-кислого позвол ет получить качественно обработанную поверхность, котора в дальнейшем обеспечивает прочное сцепление пермалло с гальваническим покрытием .It follows from the table that only the combined content of ferric chloride, ammonium citric acid and sodium or potassium in sulfuric acid in the solution allows to obtain a well-treated surface, which further provides a strong adhesion of permallo with electroplated coating.
Таким образом, предлагаемъй раствор по сравнению с известным позвол ет получить качественно пpoтpaвлeннJm и хорошо сцепл ющуюс с последующимThus, the proposed solution, in comparison with the known, allows to obtain qualitatively well-matched and well adhering with the subsequent
гальванопокрытием поверхность пермалло непосредственно в ванне травлени , исключа необходимость дополнительных химических обработок в концентрированньк кислотах, кроме того, раствор пригоден дл травлени сталей , что позвол ет его примен ть на автоматических лини х, где никелируютс одновременно стальные и пермаллоевые детали.electroplating permallo surface directly in the etching bath, eliminating the need for additional chemical treatments in concentrated acids, in addition, the solution is suitable for steel etching, which allows it to be used on automatic lines, where steel and permalloy parts are nickel-plated simultaneously.
