METHOD OF PRODUCING OXIDE COATING CONTAINING MANGANITE OF COMPOSITION LaCaMnO (0≤X≤0.4) ON A TITANIUM SUBSTRATE Russian patent published in 2024 - IPC C25D11/26 C25D15/00 

FIELD: electroplating.

SUBSTANCE: invention relates to electroplating, namely: to formation of functional manganite-containing coatings on titanium substrate with different magnetic characteristics ferro-, ferri- and antiferromagnetic. Method of producing on titanium substrate oxide coating containing manganite composition La_1-xCa_xMnO₃ (0≤x≤0.4), including plasma-electrolytic oxidation of titanium substrate in electrolyte containing 0.1 mol/l Na₂SiO₃·5H₂O and 24 g/l of lanthanum manganite powder or lanthanum-calcium manganite, wherein oxidation is carried out in anode or anode-cathode mode at current density of 0.1–0.2 A/cm² for 10–12 minutes.

EFFECT: coating on titanium substrate, containing in porous layer of TiO₂ particles of manganite-containing multiferroic, which is obtained in a single step by plasma-electrolytic oxidation in a single-component electrolyte solution in both anode and anode-cathode modes.
