Comparison Of Efficiency And Performance Of Different Plasma Torches Depositing YSZ

In this work, a method to understand the spray plume profile and explore the improvements in deposition efficiency by controlling the particle cut is presented. Different plasma torches, as well as fine and coarse cuts of HOSP and non-HOSP YSZs were used in this work. The spray plume was characterized using the in-flight measurement instrument- DPV2000 and optimized spray parameters were developed. Collected YSZ sample coupons were correlated with the DE, microstructural analysis and some key properties; i.e., porosity, microhardness and phase structure.
