Abstract

Изобретение относится к способу повышения качества изделия, изготовленного из металлического сплава на основе меди, причём в соответствии с этим способом изделие обрабатывают, по меньшей мере, в установке (3) для удаления оксидов так, что в этой установке для удаления оксидов с поверхности изделия удаляют оксиды посредством катодного восстановления. Изобретение также относится к устройству для осуществления способа по п.1 с целью повышения качества изделия, изготовленного из металлического сплава на основе меди, причём указанное устройство включает по меньшей мере установку для удаления оксидов. Это устройство включает элементы для осуществления катодного восстановления, такие как анод (6), катод (5) и электролит (11), причём доступ к катоду образовавшегося на аноде кислорода предотвращает мембрана (8), непроницаемая для кислорода.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a method for improving the quality of a product made of a metal alloy based on copper, and in accordance with this method, the product is treated, at least in the installation (3) for the removal of oxides so that in this installation for the removal of oxides from the surface of the product is removed oxides by cathodic reduction. The invention also relates to a device for implementing the method according to claim 1 in order to improve the quality of a product made of a copper-based metal alloy, said device comprising at least an installation for removing oxides. This device includes elements for cathodic reduction, such as the anode (6), the cathode (5) and the electrolyte (11), and access to the cathode of oxygen formed on the anode prevents the membrane (8), which is impermeable to oxygen. The international application was published with international search report.
