Abstract
Measured data on the temperature and velocity of Al2O3 particles of size fraction 34±6 μm in the jet emanating from a DC plasma torch with inter-electrode inserts under conditions of axisymmetric heterogeneous flow are reported. The velocity and temperature of individual particles were measured using a laser-optical diagnostic complex, which was a combination of a bifocal laser anemometer and a pyrometer based on a compact spectrometer. For measuring the temperature of individual particles in the particle-laden plasma jet, three-color pyrometry was used. The obtained data on the characteristics of particles in the jet emanating from the plasma spray torch with inter-electrode inserts equipped with a unit for radial-annular injection of powder into the plasma jet show that the implemented conditions for processing powder materials allow reaching a high homogeneity of the aggregate state of particles in the jet flow (∼ 100 % of melted particles).
