Abstract (en)
[origin: EP2610371A1] The subject of this invention is a method for producing homogeneous rhenium - nickel alloys by electrodeposition from aqueous solutions. In the method according to the invention to a sulphate nickel electrolytic bath for cathodic nickel production rhenium is introduced in the form of rhenate(VII) ions, preferably in the form of ammonium rhenate(VII) added in an amount of 2 to 100 g/dm 3 , and at a temperature of from 10 to 80°C, preferably at a temperature close to 55°C, the process of rhenium - nickel alloy electrodeposition is conducted on a cathode arranged centrally in the electrolyzer. On both sides of the cathode two insoluble anodes are placed, said cathodes preferably made of titanium and coated with metal oxides, wherein the cathodic current density is set to ‰¤ 5 A/dm 2 , with pH of the bath ranging from 1 to 8, and wherein a laminar flow of the electrolyte is effected at a linear velocity of from 1 to 5 cm/min for a volumetric charge density ranging from 1 to 5 Ah/dm 3 .
