Abstract

Thermal cycling and melt reaction studies of ceramic coatings plasma-sprayed on Nb substrates were carried out to evaluate the performance of barrier coatings for metallic fuel casting applications. Thermal cycling tests of the ceramic plasma-sprayed coatings to 1450 °C showed that HfN, TiC, ZrC, and Y₂O₃ coating had good cycling characteristics with few interconnected cracks even after 20 cycles. Interaction studies by 1550 °C melt dipping tests of the plasma-sprayed coatings also indicated that HfN and Y₂O₃ do not form significant reaction layer between U-20 wt.% Zr melt and the coating layer. Plasma-sprayed Y₂O ₃ coating exhibited the most promising characteristics among HfN, TiC, ZrC, and Y2O₃ coating.
