Suspension plasma spraying has opened new technological opportunities in the last decade, especially the possibility of the dispersion of very small particles in suspensions promises the interesting coating characteristics. Nevertheless, suspension spraying has high energetic demand due to the need of the vaporation of a solvent. The hybridly stabilized torch features extremely high-enthalpy plasma with adjustable power, so its utilization for suspension spraying is greatly convenient (the torch has been successfully used for commercial solid state spraying in Japan and in the Czech Republic). The injection of liquids (suspensions) to a plasma jet influences plasma characteristics and this paper shows the basic research of the changes of plasma properties measured by means of an enthalpy probe and emission spectroscopy
