Conclusions
-
1.
The maximum particle velocity in detonation deposition is reached at a certain optimum effective barrel length; the heating of particles increases in intensity with increase in effective barrel length, which is linked with the residence time of the particles in the hot detonation products.
-
2.
The effectiveness of powder utilization and the properties of coatings in detonation deposition are determined to a large extent by the velocity of the particles being deposited, although the character of deposit layer formation is affected also by the degree of heating of the particles.
