тем последовательного растворени в дистиллированной воде серной кислоты,the sequential dissolution of sulfuric acid in distilled water,
тиомочевины, роданистого аммони и молочной кислоты.,thiourea, rhodium ammonium and lactic acid.,
Увеличение содержани тй()мЬчевйны до 60-95 г/л позвол ет несколько повысить рабочую плотность тока и уменьшить врем проведени процесса.Increasing the content () of the mixture to 60-95 g / l makes it possible to slightly increase the operating current density and reduce the process time.
Введение роданистого аммони резко увеличивает скорость растворени металла и тем самым повьпиает производительность раствора. Одновременно при этом значительно повышаетс работоспособность раствора, что делает его пригодным дл полировани различных сплавов золота.The introduction of ammonium ammonium sharply increases the rate of dissolution of the metal and thereby increases the solution rate. At the same time, the efficiency of the solution is significantly increased, which makes it suitable for polishing various gold alloys.

Добавление молочной кислоты приводит к улучшению качества поверхностиAdding lactic acid leads to improved surface quality.
при минимальном съеме металла в широком диапазоне плотностей тока дл различных сплавов золота.with minimal metal removal in a wide range of current densities for various gold alloys.
Электролит стабилен в работе при пролускании 92-133 . В предлагаемом растворе полируют различные сплавы золота, а именно: золото - медь никель - цинк - марганец, золото - серебро - медь - плалладий, золото серебро- медь, золото- медь- никель цинк .The electrolyte is stable in operation when passing 92-133. In the proposed solution, various alloys of gold are polished, namely: gold – copper, nickel – zinc – manganese, gold – silver – copper – plaladium, gold silver – copper, gold – copper – nickel zinc.
Конкретные примеры использовани предлагаемого раствора представлены в таблице.Specific examples of the use of the proposed solution are presented in the table.
