Изобретение относитс к электрохимической размерной обработке алюминиевых сплавов, в частности типа .АМг-6.This invention relates to the electrochemical dimensional processing of aluminum alloys, in particular of the type AMG-6.
Известны электролиты, примен емые дл электрохимической размерной обработки алюминиевых сплавов, на основе водных растворов нитратов или хлоридов натри .Electrolytes used for the electrochemical dimensional processing of aluminum alloys based on aqueous solutions of sodium nitrates or sodium chlorides are known.
Однако с помощью известных электролитов невозможно получить высокую скорость обработки (не менее 4-5 мм/мин) при чистоте обработанной поверхности не менее 7 8, отсутствии микродефектов и межкристаллитного растравливани .However, using known electrolytes, it is impossible to obtain a high processing rate (at least 4-5 mm / min) with a cleaned surface of at least 7 8, no microdefects and intergranular etching.
Цель изобретени - повышение производительности и качества обработанной поверхности .The purpose of the invention is to increase the productivity and quality of the treated surface.
Это достигаетс тем, что в состав предлагаемого электролита на основе водного раствора нитрата натри введен хлорид натри при соотношении компонентов, вес, %:This is achieved by the fact that sodium chloride is added to the composition of the proposed electrolyte based on an aqueous solution of sodium nitrate at a ratio of components, weight,%:
Нитрат натри 29-31Sodium nitrate 29-31
Хлорид натри 2,8-3,2Sodium chloride 2.8-3.2
ВодаОстальное.Water the rest.
Процесс обработки в предлагаемом электролите осуществл етс при плотности тока 80- 160 а/см температуре электролита 40-45°С,The treatment process in the proposed electrolyte is carried out at a current density of 80-160 A / cm electrolyte temperature of 40-45 ° C,
рН 7-11, скорости протока электролита в зоне обработки не менее 40 м/сек и межэлектродном зазоре 0,15-0,25 мм. В результате электрохимической размерной обработки алюминиевых сплавов типа АМг-6 в предлагаемом электролите при указанном режиме достигаетс производительность до 5 мм/мин, выход по току, равный 145-148%, чистота поверхности пор дка 9-10 при отсутствии макродефектов и межкристаллитного растравливани , что значительно, превышает соответсгвующие показатели, достигаемые при обработке в известных электролитах.pH 7-11, the flow rate of the electrolyte in the treatment area is not less than 40 m / s and the electrode gap is 0.15-0.25 mm. As a result of the electrochemical dimensional processing of aluminum alloys of the AMg-6 type in the proposed electrolyte, with the specified mode, a performance of up to 5 mm / min is achieved, a current efficiency of 145-148%, a surface purity of about 9-10 in the absence of macrodefects and intergranular etching, which significantly exceeds the corresponding indicators achieved by processing in known electrolytes.
