Description
Изобретение относитс к химической обработке металлов, в частности к области химического размерного травлени и может быть использовано в различиых отрасл х машиностроени .The invention relates to the chemical treatment of metals, in particular, to the field of chemical dimensional etching and can be used in various fields of engineering.
Известен раствор дл глубокого травлени алюминиевых сплавов, содержаи ий едкий натр и фторид щелочного металла.Known solution for deep etching of aluminum alloys containing caustic soda and alkali metal fluoride.
Предложенный раствор отличаетс от известного введением в его состав надсернокислого аммони , гипосульфита натри и алюмини при онределенном соотношении компонентов , что позвол ет повысить качество поверхности и интенсифицировать процесс.The proposed solution differs from the known one by introducing ammonium sulphate, sodium hyposulphite and aluminum into its composition at a predetermined ratio of components, which allows to improve the surface quality and intensify the process.
Раствор содержит едкий натр, фтористый калий, надсернокислый аммоний, гипосульфит натри и алюминий при следующем соотношении компонентов, The solution contains sodium hydroxide, potassium fluoride, ammonium persulphate, sodium hyposulfite and aluminum in the following ratio of components,
Едкий натр250-300Caustic soda 250-300
Калий фтористыйб-8Potassium fluoride-8
Аммоний надсернокислый15-18Ammonium sulfate15-18
Гипосульфит натри 25-30Sodium Hyposulphite 25-30
Алюминий10-15.Aluminum 10-15.
Травление в предлагаемом растворе проводитс нри 85-90°С.Etching in the proposed solution is carried out at 85-90 ° C.
Предлагаемый раствор обеспечивает глубокое травление алюминиевых снлавов типа В-95 и Д-16 на глубину свыше 2 мм с достаточно чистой поверхностью (V5-V6). Скорость травлени 0,05-0,07 мм/мин.The proposed solution provides deep etching of aluminum snlavov of type B-95 and D-16 to a depth of over 2 mm with a fairly clean surface (V5-V6). The etching rate of 0.05-0.07 mm / min.
