Изобретение относитс к электрохимически размерной обработке металлов и сплавов.This invention relates to electrochemically sized machining of metals and alloys.
Известны способы электрохимической обработки , по которым предусматриваетс удаление с обработанных поверхностей пленки продуктов анодного растворени с помощью ультразвуковых колебаний. Недостатками этого способа вл ютс недостаточна эффективность удалени пленки и необходимость применени сложного специального ультразвукового оборудовани .Electrochemical treatment methods are known that provide for the removal of anodic dissolution products from the treated surfaces of the film using ultrasonic vibrations. The disadvantages of this method are the insufficient removal efficiency of the film and the need to use sophisticated specialized ultrasound equipment.
Цель изобретени - обеспечение возможности удалени пленки продуктов анодного растворени .The purpose of the invention is to provide the possibility of removing the film of anodic dissolution products.
Это достигаетс путем применени дополнительной обработки издели , прошедшего электрохимическую обработку в iNaCl, в электролите , представл ющем собой 5%-ный водный раствор NaOH. Процесс удалени ведут на той же позиции, что и электрохимическую обработку .This is achieved by applying an additional treatment to the product that has undergone electrochemical treatment in iNaCl in an electrolyte, which is a 5% aqueous solution of NaOH. The removal process is carried out in the same position as the electrochemical treatment.
Сущность способа заключаетс в следующем .The essence of the method is as follows.
После электрохимической обработки на той же позиции, например, путем переключени вентилей в зону обработки подаетс электролит в виде 5%-ого водного раствора гидрата окиси натри . Получивша с рыхла пленка продуктов анодного растворени удал етс и образуетс нова оксидна пленка, способствующа повышению коррозионной стойкости обработанной поверхности.After electrochemical treatment at the same position, for example, by switching the valves to the treatment area, the electrolyte is supplied in the form of a 5% aqueous solution of sodium hydroxide. The loose film of anodic dissolution products is removed and a new oxide film is formed, which contributes to an increase in the corrosion resistance of the treated surface.
Процесс удалени производ т на обычных режимах технологического тока, примен емых при электрохимической обработке металлов.The removal process is carried out at the usual technological current conditions used in the electrochemical machining of metals.
Предмет изобретени Subject invention
Способ электрохимической обработки в хлоридных электролитах, отличающийс тем, что, с целью удалени пленки продуктов анодного растворени , осуществл ют дополнительный съем металла в 5%-ном водном растворе окиси натри .The method of electrochemical treatment in chloride electrolytes, characterized in that, in order to remove the film of anodic dissolution products, an additional removal of the metal in a 5% aqueous solution of sodium oxide is carried out.
