FIELD: chemistry.
SUBSTANCE: in accordance with the method a coating is formed from a tantalum-containing organic solution, as such used is an extract, obtained by extraction of tantalum with sulphates of long-chained tertiary amines or quaternary ammonium bases from sulfate oxalate tantalum solution, with application of extract on substrate and realisation of substrate burning at temperature 600-700°C. In accordance with the method before application on substrate extracts are preliminarily evaporated to distil solvent until oil-like extract is obtained.
EFFECT: application of extraction-pyrolytic method makes it possible to simplify formation of Ta2O5 coatings on titanium substrates.
