Изобретение относитс  к электрохимической обработке изделий, в частности к электрохимическому травлению изделий из сталей. Известен способ электрохимического травлени  изделий из сталей в растворе на основе едкого кали. Однако качество обрабатываемой поверхности низкое.This invention relates to the electrochemical treatment of articles, in particular, to the electrochemical etching of articles from steels. The known method of electrochemical etching of steel products in a solution based on caustic potash. However, the quality of the treated surface is low.

Данный способ позвол ет получать качественную поверхность, без растравливани  основного металла.This method allows to obtain a high-quality surface without etching the base metal.

Предложенный способ отличаетс  от известного тем, что в раствор ввод т ортофосфат кали , нитрит «али , хелатон - 3, при следующем соотношении компонентов, г/л: Едкое кали80-120The proposed method differs from the well-known fact that potassium orthophosphate, nitrite, ali, chelate - 3 are introduced into the solution, in the following ratio of components, g / l: Caustic potassium 80-120

Ортофосфат кали 20- 40Potassium orthophosphate 20-40

Нитрит кали 20- 40Potassium Nitrite 20-40

Хелатон - 340- 60Chelaton - 340- 60

и процесс ведут 18-60° С, плотности тока 250-750 а/дм.and the process is 18-60 ° C, current density 250-750 a / dm.

После щелочного травлени  провод т кислотное травление в электролите следующего состава, г/л:After alkaline etching, acid etching is carried out in an electrolyte of the following composition, g / l:

Азотна  кислота100-120Nitric acid100-120

Серна  кислота200-240Sulfuric acid200-240

Лимониоаммиачное железо 30- 50Limonioammic iron 30-50

и процесс ведут при 18-60° С, плотности токаand the process is carried out at 18-60 ° C, current density

250-750 а/дм.250-750 a / dm.

Процессы щелочного и кислотного травлени  изделий из нержавеющих сталей провод т электронатрианием.The processes of alkaline and acid etching of stainless steel products are carried out by elec tronization.

Данный способ позвол ет совместить процессы разрыхлени  и травлени  окислов сThis method allows combining the processes of loosening and etching of oxides with

операци ми обезжиривани , осветлени  и пассивировани  поверхности изделий.degreasing, clarifying and passivating the surface of products.

Дл  повышени  эффективности процесса травлени  и получени  качественных осветленных поверхностей, защищенных пассивнойTo increase the efficiency of the etching process and to obtain high-quality clarified surfaces protected by passive

пленкой, растворы в процессе травлени  чередуют , при условии начала и окончани  процесса обработкой щелочным раствором.film, the solutions in the process of etching alternate, subject to the beginning and end of the process by treatment with an alkaline solution.
