ABSTRACT:
The invention relates to the technology of applying a coating of powder materials by spraying and can be used for producing a coating of metals; their mechanical mixtures and dielectrics, adding various functional properties to treated surfaces. The proposed method of applying a powder coating comprised as follows: producing a gas-carrier flow, mixing powder with it, accelerating the gas-powder flow in the nozzle, generating its preset profile, further simultaneously generating the second gas-carrier flow, heating it, generating its preset profile and accelerating it in the nozzle, after that superimposing the accelerated gas-powder flow of the preset profile over the gas-carrier flow of the preset profile, and directing the cumulative jet to an article.
