Изобретение относится к устройствам для сверхзвукового газопламенного напыления покрытий и содержит камеру сгорания со сверхзвуковым соплом, систему подачи горючего и окислителя в камеру сгорания, магистраль подвода порошка в сверхзвуковой поток продуктов сгорания, и узел смешения последних с порошком. Для повышения равномерности распределения частиц порошка по поперечному сечению потока, снижения затрат энергии на разгон последнего и исключения налипания частиц порошка на стенки установки, узел смешения выполнен в виде патрубка с поперечным сквозным каналом в его боковой стенке, сопло имеет форму сопла Лаваля и примыкает срезом к торцу патрубка с образованием с последним единого проточного тракта, а магистраль подвода порошка сообщена с каналом, при этом внутренняя поверхность тракта в месте стыка патрубка со срезом сопла имеет излом.The invention relates to a device for supersonic gas-flame spraying of coatings and comprises a combustion chamber with a supersonic nozzle, a fuel and oxidizer supply system to the combustion chamber, a powder supply line to a supersonic flow of combustion products, and a unit for mixing the latter with the powder. To increase the uniformity of the distribution of powder particles over the cross section of the flow, reduce the energy consumption for accelerating the latter and to prevent sticking of powder particles to the walls of the installation, the mixing unit is made in the form of a pipe with a transverse through channel in its side wall, the nozzle has the shape of a Laval nozzle and adjoins the cut to the end of the nozzle with the formation of a single flow path with the latter, and the powder supply line is in communication with the channel, while the inner surface of the path at the junction of the nozzle with the nozzle exit has a m.
