FIELD: technological processes.
SUBSTANCE: group of inventions relates to high-emissive coating compositions and methods of their production. Thermionic coating composition for a substrate includes a dry mixture of substances increasing emission capacity of the coating, herewith the substances increasing emission capacity of the coating contain titanium dioxide, and substances, which increase mechanical strength. In another version the composition additionally contains a solution-based component containing phosphoric acid. Method of producing the coating involves determination of a specified level of the coating emission capacity, determination of concentration of titanium dioxide, determination of adhesion properties and manufacturing of the thermionic coating composition.
EFFECT: technical result is increased heat emission by radiation.
