| Abstract: |
Due to the significant effect of in-flight particle size on the microstructure and properties of the atmospheric-plasma-sprayed coatings, a study of the in-flight particle size distribution in plasma jet is important. In this paper, 316L stainless steel powders with different size ranges were used as the feedstocks. In-flight particles were collected at different spray distances by water. The particle size distribution was measured, and the surface morphology of the particles was investigated by scanning electron microscopy. Results showed that the effect of vaporization and impact of the plasma jet on the in-flight particle size was obvious. It was also found that the size ranges of the feedstock powders can also affect the size of the in-flight particles.
