Description
Известные способы электрохимической обработки поверхности алюмини и сплавов на его основе в растворах, содержащих хлористые со ,ли, не дают возможности регулировать стеиень чистоты и шероховатости поверхности обработанного Издели .Known methods of electrochemical treatment of the surface of aluminum and alloys based on it in solutions containing chloride so, li, do not make it possible to adjust the stieni of purity and surface roughness of the treated article.
Описываемый электролит дл электрохимического травлени алюмини и его сплавов, содержащий хлористые соли, позвол ет придавать поверхности изделий из этих материалов любую, заранее задаваемую, степень шероховатости.The described electrolyte for electrochemical etching of aluminum and its alloys, containing chloride salts, makes it possible to impart to the surface of products made from these materials any degree of roughness that can be predetermined.
Достигаетс это тем, что в состав электролита, состо щего из насы щенного водного раствора поваренной соли, по мере надобности ввод т добавки кислот или щелочей, количество которых регулируетс в зависимости от степени шероховатости поверхности.This is achieved by the fact that the composition of the electrolyte consisting of a saturated aqueous solution of sodium chloride, as necessary, add additives of acids or alkalis, the amount of which is regulated depending on the degree of surface roughness.
При электрохимическом травлении в описываемом электролите обрабатываемое изделие вначале дл лучшей очистки от жиров и посторонних примесей включаетс в качестве катода на некоторое врем , по,: ле чего направление тока измен ют и осуществл ют анодную обработку издели . После того как изделие покроетс черным налетом гидрата окиси алюмини направление тока еще раз измен ют, в результате чего налет удалитс . Продолжительность травлени на каждом перечислен ном этапе устанавливают экспериментально в каждом отдельном случи и зависимости от состава сплава и необходимой шероховатости поверх ности издели . Применение трехстадийного травлени не об зательно Возможно ограничитьс одностадийной анодпой обработкой.In the case of electrochemical etching in the described electrolyte, the product to be processed is first included for a better cleaning of fats and impurities as a cathode for some time, so that the current direction is changed and the product is anodized. After the product is covered with a black bloom of alumina hydrate, the direction of the current is once again changed, resulting in the plaque being removed. The duration of etching at each listed stage is established experimentally in each case and depending on the composition of the alloy and the required surface roughness of the product. The use of three-stage etching is not necessary. It is possible to limit it to one-stage anodic treatment.
