Abstract
The heat balance of a water calorimeter absorbing the energy of a plasma jet with sprayed metal particles (Al, Cu, Fe, powder steel, and bronze) is analyzed. It was established that, in all cases, the temperature of the air-plasma jet with sprayed particles reaches the boiling temperature of the metal, a part of which passes into the vaporous state. As a result of the exothermic reaction of aluminum oxidation within the airplasma stream, the energy of the plasma jet increases by approximately two times and by ∼20% at spraying the powder steel wire. It is shown that 17–25% of the plasma-sprayed metal is evaporated or oxidized (burned out).
