ELECTROLYTE SOLUTION AND ELECTROCHEMICAL METHODS OF SURFACE MODIFICATION |
| abstract |
An aqueous electrolyte solution comprising citric acid with a concentration in the range from about 1.6 g / l to about 982 g / l and ammonium hydrodifluoride (HFA) with an effective concentration and practically free of strong acid. Methods for treating the surface of a non-ferrous metal billet include exposing the surface to a bath with an aqueous electrolyte solution comprising citric acid with a concentration less than or equal to about 300 g / l and ammonium hydrodifluoride with a concentration greater than or equal to about 10 g / l and having not more than about 3 , 35 g / l of strong acid, regulation of the bath temperature greater or equal to about 54 ° C, connection of the workpiece to the anode of the DC power source and immersion of the cathode of the DC power source in annihilated and passing current through the bath. |
