Efficiency of micron-sized particles heating in high enthalpy plasma jets
Heterogeneous plasma flows are widely used for heating of particles and plasma spraying. Wide temperature and dynamic range of plasma jets, the possibility of using different working gases allow combining in a single technological process phase and chemical transformations to ensure the desired modification of the initial powders and coating materials with a given structure [1]. Plasma spraying - an extremely high technology, which potential, due to insufficient knowledge chain "plasma - the injection of powdered material - a dusty plasma jet - cover - his subsequent heat treatment, are currently used not full. Progress in this area can only be achieved by setting the integrated research, consistently across all links of the chain forming a stable final product with predetermined properties, which are guaranteed not only in the laboratory, but also in industrial conditions.
