In this work, the spraying behavior of a copper powder in the Computer-Controlled Detonation Spraying (CCDS) process was studied both theoretically and experimentally. The dependences of the particle temperatures and velocities on the explosive charge were calculated for particles of copper 40 μm in diameter for different O2/C2H2 ratios (1.1; 1.5; 2.0; 2.5) and nitrogen and air as carrier gases using models and software previously developed at Lavrentyev Institute of Hydrodynamics SB RAS. The explosive charge was varied between 30 and 60% of the barrel volume. Calculations showed that the particle temperatures increase and the particle velocities decrease monotonously as the O2/C2H2 ratio increases from 1.1 to 2.5 at a constant explosive charge when nitrogen is used as a carrier gas. It was shown that the choice of the carrier gas (nitrogen or air) significantly influences the temperature of the particles when spraying is conducted at a low O2/C2H2 ratio. In this case, the particle velocities are also affected. For experiments, an electrolytic copper powder with an average size of 40 μm was used. The morphological features of the deposits were such that could be well expected in the deposits formed by particles heated up to the calculated temperatures.
