Изобретение относитс к получени декоративных покрытий на меди и может найти применение при изготовлении изделий культурно-бытового назначени .The invention relates to the production of decorative coatings on copper and can be used in the manufacture of articles of cultural and domestic purposes.
Цель изобретени - окрашивание меди в коричневый цвет и повышение стабильности окраски.The purpose of the invention is to dye copper brown and increase color stability.
Электролит дл анодного окрашивани меди, содержащий соль металла и воду, в качестве соли металла содержит железистосинеродистый калий.The electrolyte for the anodic staining of copper, containing a metal salt and water, contains ferrous and sintered potassium as the metal salt.
Анодную обработку провод т при плотности тока 0,1-1,0 А/дм и комнатной температуре в течение 3 мин.Anodic treatment is carried out at a current density of 0.1-1.0 A / dm and at room temperature for 3 minutes.
Окрашивание меди в коричневый цвет происходит в результате анодного растворени меди и последующего взаимодействи ионов меди с ферроци нидом с образованием ферроцианида меди коричневого цвета.Brown coloring of copper occurs as a result of the anodic dissolution of copper and the subsequent interaction of copper ions with ferrocyanide to form brown copper ferrocyanide.

обусловлен началом пассивации меди, снижением равномерности и интенсивности окраски. Повышение концентрации железистосийеродистого кали бо5 лее 50 г/л нецелесообразно, так как это не вли ет на процесс окрашивани .due to the beginning of the passivation of copper, reducing the uniformity and intensity of color. An increase in the concentration of ferrous and fibrous potassium more than 50 g / l is impractical because it does not affect the staining process.
В табл. 1 приведены данные по составу предлагаемого злектролита иIn tab. 1 shows the data on the composition of the proposed electrolyte and

В табл. 2 представлены данные, подтверждаюпще стабильность коричневого цвета и более высокую корро15 зионную способность пленок, полученных из предлагаемого злектролита.In tab. Figure 2 presents the data confirming the brown color stability and the higher corrosion ability of the films obtained from the proposed electrolyte.
Как видно из табл. 1 и 2, предлагаемый электролит приводит к окрашиванию поверхности меди в стабильныйAs can be seen from the table. 1 and 2, the proposed electrolyte leads to staining of the copper surface in a stable
20 коричневый цвет. В зависимости от величины плотности тока и времени обработки могут быть получены различные оттенки коричневого цвета.20 brown color. Depending on the magnitude of the current density and processing time, different shades of brown can be obtained.
