ЭЛЕКТРОЛИТ ДЛЯ ЭЛЕКТРОХИМИЧЕСКОЙ ОБРАБОТКИELECTROLYTE FOR ELECTROCHEMICAL TREATMENT
1one
Изобретение касаетс технологии электрохимической обработки металлов и может быть использовано при размерной обработке титановых сплавов.The invention relates to the technology of electrochemical machining of metals and can be used for dimensional processing of titanium alloys.
Известны электролиты дл обработки титановых сплавов, которые представл ют собой растворы хлористого натри или смеси его с азотпокислым натрием с различными добавками. Однако существующие электролиты при обработке титановых сплавов не обеспечивают необходимого качества поверхности .Electrolytes are known for treating titanium alloys, which are solutions of sodium chloride or a mixture of it with sodium nitrate with various additives. However, existing electrolytes in the processing of titanium alloys do not provide the required surface quality.
Дл разработки состава электролита, позвол ющего улучшить качество обрабатываемой поверхности и обеспечени равномерного растворени титановых сплавов в электролит , содержащий смесь хлористого и азотнокислого натри , вводитс соль йодистоводородной кислоты (HJ) до предела растворимости при оптимальной конпентрации дл йодистого натри от 3,0 до 7,0%, дл йодистого кали от 2,5 до 5%.To develop an electrolyte composition that improves the quality of the surface to be treated and ensure uniform dissolution of titanium alloys, an iodide salt (HJ) is added to the electrolyte containing a mixture of sodium chloride and sodium nitrate to the limit of solubility at an optimum concentration for sodium iodide from 3.0 to 7, 0%, for potassium iodide from 2.5 to 5%.
Так, например, в электролит, содержащий смесь 10%-ного хлористого натри и 10%ного азо№окислого натри Добавл ют йодистый калий 2,5%. Процесс ведут при давлении электролита 1-4 кг/см и напр жении 4,0 в на установке с вибрирующим латунным катодом и импульсной подачей тока. Температура электролита 18--30° С. В результате обработки получена поверхность дев того класса чистоты . Участков с замедленной скоростью растворени не наблюдаетс .For example, potassium iodide 2.5% is added to an electrolyte containing a mixture of 10% sodium chloride and 10% azo sodium sulfate. The process is carried out at an electrolyte pressure of 1–4 kg / cm and a voltage of 4.0 V on an installation with a vibrating brass cathode and a pulsed current supply. The electrolyte temperature is 18--30 ° C. As a result of processing, a surface of the ninth class of purity has been obtained. No sites with a slow dissolution rate were observed.
