METHOD FOR PRODUCING MECHANICALLY STRONG SUPERHYDROPHOBIC SURFACES BASED ON TWO-LAYER ELECTROPLATING WITH MATRICES OF COPPER AND CHROMIUM Russian patent published in 2023 - IPC C25D15/00 C25D5/12 C25D3/38 C25D3/06 

FIELD: electroplating.

SUBSTANCE: multilayer electroplating, namely to the production of superhydrophobic coatings. The method includes electrochemical deposition of a copper composite, electrochemical deposition of chromium or a chromium composite, surface treatment in an alcohol solution of stearic or lauric acid. Electrochemical deposition of a copper composite is carried out from an electrolyte containing CuSO₄, H₂SO₄, sodium lauryl sulfate or synthanol and nanodispersed MoS₂ particles. Electrochemical deposition of chromium or a chromium composite is carried out from an electrolyte containing KCr(SO₄)₂, Al₂(SO₄)₃, Na₂C₂O₄, NaF, which additionally contains nanodispersed particles of Cr₂O₃ for deposition of the chromium composite.

EFFECT: obtaining a mechanically stable superhydrophobic coating.
