ACID ELECTROLYTE AND THE METHOD OF THE ELECTROLYTIC DEPOSITION OF THE SATIN NICKEL COATINGS Russian patent published in 2007 - IPC C25D3/12 

FIELD: electrochemical industry; galvanostegy; production of the acid electrolyte and the methods of the electrolytic deposition of the satin nickel coatings.

SUBSTANCE: the invention is pertaining to the galvanostegy. The electrolyte contains at least one compound of the quaternary ammonium and at least one polyether. At that the indicated polyester contains at least one highly hydrophobic side chain. The method provides for contacting of the substrate with the indicated electrolyte and the electric current gating between substrate and the anode. The technical result of the invention is provision of the long time exploitation of the electrolyte at the low concentration of the ions of the nickel and the electrolyte hyposensitivity to the added wetting agents. At that the realization of the heating-cooling cycles, filtration cycles with the capability of the continuous exploitation of the electrolyte without usage of the active coal takes place.

EFFECT: the invention ensures the long time exploitation of the electrolyte at the low concentration of the ions of the nickel and the electrolyte hyposensitivity to the added wetting agents.
