METHOD OF ELECTROLYTIC DEPOSITION OF IRON-COBALT ALLOY Russian patent published in 2017 - IPC C25D3/56 

FIELD: electricity.

SUBSTANCE: method comprises depositing a coating of an electrolyte containing iron chloride 350-400 kg/m³, cobalt chloride 5-50 kg/m³, hydrochloric acid 0.5-2.0 kg/m³ and water on an alternating asymmetric current with current asymmetry coefficient of 1.2-6.0 at an electrolyte temperature of 30-50°C. Sodium chloride in an amount of 5-20 kg/m³ is administered into the electrolyte composition, and the deposition is carried out in the interval of cathode current densities of 60-100 A/dm².

EFFECT: increasing the stability of the electrolyte, preventing its rapid oxidation, increasing the electrical conductivity of the electrolyte and the rate of the coating deposition.
