METHOD TO APPLY COATINGS Russian patent published in 2012 - IPC C23C14/22 B82B3/00 

FIELD: machine building.

SUBSTANCE: method includes installation of a plasmatron into a chamber with lower pressure, arrangement of a substrate for coating application in a chamber, maintenance of dynamic vacuum in the chamber, supply of plasma-forming gas and powder of sprayed material into the plasmatron and spraying of material by supersonic flow of plasma in the chamber to form melted particles of powder and steam phase of the sprayed material. In front of the substrate, onto which a coating is applied, a mask with holes and links between them is installed, flow of steam phase of a sprayed substance is ensured around links, underpressure waves are developed behind the links, where the steam phase condenses to form nanoparticles, which drop onto the substrate and form a coating in the form of narrow strips made only of nanoparticles and arranged around sections of the coating provided oppositely to the mask holes from powder particles. The mask is moved relative to the applied coating, and subsequent layers of the coating are generated on the applied layer to produce a coating with a structure of several applied layers.

EFFECT: improved working characteristics of a coating under multiple thermocyclic loads.
