Barrels of units for detonation spraying of coatings

Yu.A. Kharlamov

East-Ukrainian National University, Lugansk, Ukraine

Abstract
The paper deals with the advantages of technological application of detonation modes of gas mixture combustion, chiefly for thermal spraying of coatings, as well as various design features of combustion chambers of the coating units. Feasibility of developing the processes of spraying of coatings, using cylindrical detonation waves, and also using continuous gas detonation, is noted.
Keywords: thermal spraying, detonation in gases, detonation-gas spraying, barrels, detonation guns
