Ey. Shkol'Nikov et al., Acceleration of microparticles in an electrothermal accelerator with a multigap scheme of the discharge unit, INSTR EXP R, 43(6), 2000, pp. 846-851
The results of an experimental study of pulsed streams generated by an elec
trothermal launcher and the acceleration dynamics of microparticles in thes
e hows are described. The experimental data obtained, in particular, by usi
ng laser probing of flows have confirmed that microparticles are captured a
nd accelerated by the gas flow region following the head shock wave. The us
e of a multigap design of the accelerator discharge unit allowed for effici
ent formation of this region. Analyzing the coatings from powder materials
deposited with the help of the electrothermal launcher has demonstrated the
possibility of obtaining high-quality coatings.
