摘要:
A process for regenerating electrolytes containing high sodium chloride concentrations for reuse in the production of an electrochemical polishing process of aluminum surfaces.
摘要:
The invention refers to a method for the electrochemical machining of work pieces, such as, for example, nozzles, in particular nozzles with a blind hole. The invention also refers to a device for the electrochemical machining of work pieces.The invention is characterized by a relative movement, in particular a rotary movement during the machining between work piece and cathode. The device is characterized in that cathode and/or work piece are supported rotatably on bearings for a relative movement.

摘要:
The invention refers to a process for regenerating electrolytes containing sodium nitrate for use in the electrochemical working of metallic workpieces within the pH range from 4 to 12.Iron (III) nitrate is added to the electrolyte in the working cycle in such an amount that the hydrolysates are predominantly precipitated in coarse flocculent form. Flocculents may be added to the electrolyte.
