Abstract

Водный раствор электролита, включающий лимонную кислоту с концентрацией в диапазоне от примерно 1,6 до примерно 982 г/л и гидродифторид аммония (ГФА) с эффективной концентрацией и практически не содержащий сильной кислоты. Способы обработки поверхности заготовки из цветного металла включают подвергание поверхности воздействию ванны с водным раствором электролита, включающим лимонную кислоту с концентрацией меньшей или равной примерно 300 г/л и гидродифторид аммония с концентрацией большей или равной примерно 10 г/л и имеющим не более чем примерно 3,35 г/л сильной кислоты, регулирование температуры ванны большей или равной примерно 54°С, подключение заготовки к аноду источника питания постоянного тока и погружение катода источника питания постоянного тока в ванну и пропускание тока через ванну.An aqueous electrolyte solution comprising citric acid at a concentration in the range of about 1.6 to about 982 g / L and ammonium hydrodifluoride (HFA) at an effective concentration and practically free of strong acid. Methods for treating the surface of a non-ferrous metal preform include exposing the surface to a bath of an aqueous electrolyte solution comprising citric acid at a concentration less than or equal to about 300 g / L and ammonium bifluoride at a concentration greater than or equal to about 10 g / L and having no more than about 3 , 35 g / L strong acid, adjusting the bath temperature to about 54 ° C, connecting the workpiece to the anode of the DC power supply, and immersing the cathode of the DC power supply in the bath and passing current through the bath.
