Abstract

Изобретение относится к технологии нанесения покрытий на поверхности изделий, а именно к газодинамическим способам нанесения покрытий с использованием неорганического порошка, и может быть использовано в различных отраслях машиностроения. Сжатый газ поступает в нагреватель 1, где нагревается до необходимой температуры, обеспечивающей отсутствие налипания частиц на стенки сопла. Нагретый сжатый газ подается в сверхзвуковое сопло 2, в котором проходит последовательно сужающийся участок, горло 3, расширяющийся участок сопла и ускоряется до сверхзвуковой скорости. В этот сверхзвуковой поток газа через элементы 5 для ввода порошков в сопло вводятся порошки напыляемого материала. Частицы порошков ускоряются высокоскоростным потоком газа на ускоряющем участке 7 сопла и далее направляются на поверхность основы. Сущность изобретения заключается в том, что установлены параметры участка сопла, расположенного после элементов для ввода порошков и предназначенного для ускорения порошков, при которых обеспечивается увеличение коэффициента напыления при сохранении возможности использования повышенной температуры сжатого газа и использования порошков, содержащих твердые частицы.The invention relates to the technology of coating on the surface of products, namely, gas-dynamic methods of coating with the use of inorganic powder, and can be used in various branches of engineering. Compressed gas enters the heater 1, where it is heated to the required temperature, ensuring the absence of sticking of particles on the walls of the nozzle. The heated compressed gas is supplied to the supersonic nozzle 2, in which the successively narrowing section passes, the throat 3, the expanding section of the nozzle and is accelerated to supersonic speed. Powders of the sprayed material are introduced into this supersonic gas flow through the elements 5 for the introduction of powders into the nozzle. The powder particles are accelerated by a high-speed gas flow in the accelerating portion 7 of the nozzle and then sent to the surface of the substrate. The essence of the invention lies in the fact that the parameters of the nozzle section, located after the elements for entering the powders and intended to accelerate the powders, are established, at which an increase in the sputtering coefficient is ensured while maintaining the possibility of using an elevated temperature of compressed gas and using powders containing solid particles.
