Abstract
The equipment of the polygon for the study of heat transfer in natural coatings was developed. A flow line for coating application was created. Quartzites, granites and teshenites were chosen as natural materials. A thermal tool with detonation jet was created and the technology of powder production by crushing in a closed volume was developed. The burner has an automatic device for controlling the mode of operation. Powders were prepared in molds made of elliptical surfaces with different eccentricity. The technology increases the powder yield of (0÷2)×10-3 m class and increases the degree of powder hardening. The automatic device sets the optimal distance to the coating, forms the optimal spot of the jet spreading. The technology provides for water ejection onto the coating. The transverse velocity of the ignition area of the spin detonation plume is determined from the inclination to the spiral trace. There is stabilization of combustion due to braking on the coating. Studies using holographic interferometry have shown that it is useful in predicting coating failure. The coatings with three heat sources is a screen that absorbs the heat tool torch waves. The coating provides erosion resistance. Spin detonation torch due to partial melting of coating particles significantly reduces particle fracture at coating interfaces.
