A Comparison of Microstructure and of Thermal Transport Properties of Yttria and Ceria Stabilized Zirconia Coatings Deposited by Suspension Plasma Spraying Available to Purchase

In this study, 8YSZ and 24CeYSZ coatings were deposited on stainless steel by suspension plasma spraying. The suspensions were formulated using finely milled powder, water, and ethanol. Spraying parameters were modified by changing spray distance and torch scan speed and were the same for each material. Coating microstructure, phase composition, and porosity were assessed and thermal diffusivity was measured and used to calculate thermal conductivity.
