FIELD: chemistry.
SUBSTANCE: method includes preliminary chemical treatment of an initial surface, applying a nickel-phosphorus film and subsequent oxidation thereof in acidic solutions. A gold layer with thickness of 1-5 mcm is deposited on the surface of the component before applying the nickel-phosphorus film.
EFFECT: high homogeneity and reproducibility of absorption properties of the formed coatings and enabling repeated deposition processes.
