ADVANCED MATERIALS & PROCESSES | MARCH 2026 48 iTSSe TSS iTSSe TSS FEATURE / TSS NEWS • The larger particle size and speckle formation can affect the coating properties, a measurable decrease in deposition efficiency, and an increase in surface roughness. ~iTSSe Acknowledgments This work was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – project number 501838742. The authors would like to thank Mr. Karl-Heinz Rauwald for operating the spray facility and Dr. Doris Sebold (both IMD-2) for the scanning electron microscopy imaging.
