Description
Изобретение относитс к области электрохимической обработки изделий, в частности к электрохимической размерной обработке сталей.This invention relates to the field of electrochemical machining of articles, in particular, to electrochemical dimensional machining of steels.
Известен способ электрохимической обработки сталей в растворе на основе хлористого натри . Однако качество поверхности, обработанной по известному способу, низкое.The known method of electrochemical machining of steels in a solution based on sodium chloride. However, the quality of the surface treated by a known method is low.
Иредлол енный способ отличаетс от известного тем, что с целью улучшени качества обрабатываемой поверхности и увеличени производительности процесса в электролит ввод т азотнокислый натрий, при соотношении компонентов, г/л; азотнокислый натрий 590-610; хлористый натрий 140-160, и процесс ведут при анодной плотности тока 4- 15 а/см2 и скорости протока электролита не выше 5 м/сек.The irradiated method differs from the well-known one in that, in order to improve the quality of the treated surface and increase the productivity of the process, sodium nitrate is introduced into the electrolyte, with a ratio of components, g / l; sodium nitrate 590-610; sodium chloride 140-160, and the process is carried out at an anode current density of 4-15 A / cm2 and the flow rate of the electrolyte is not higher than 5 m / s.
Так, при обработке стали Х18Н9Т в электролите , содержаш.ем, г/л: азотнокислый натрий 600; хлористый .натрий 150 при анодной плотности тока 4-15 а/сл1 и скорости протока электролита не выше 5 м/сек, качество обработанной поверхности соответствует 7- 9-му классам.So, when processing steel Х18Н9Т in electrolyte, containing, g / l: sodium nitrate 600; sodium chloride 150 at an anode current density of 4–15 A / c1 and an electrolyte flow rate not higher than 5 m / s, the quality of the treated surface corresponds to grades 7–9.
Предложенный способ может быть иримепен также дл электрохимического травлени The proposed method can be irimepene also for electrochemical etching
стали в непроточной ванне, при этом плот«ость тока должна поддерживатьс от 1 а/см.steel in a non-flowing bath, while the density of the current should be maintained from 1 A / cm.
