| Abstract: |
Rare earth tantalum zirconia oxide compositions especially within the TaO2.5-YO1.5-ZrO2 system offers attractive properties such as: (i) superior phase stability; (ii) low thermal conductivity and (iii) fracture toughness for the next generation thermal barrier coatings (TBCs). However, it is noteworthy the lack of data regarding their processing at industrial scales and performance tests to provide consistent information for their development as TBCs. Therefore, the objective of the present study is to manufacture a strain-tolerant porous-columnar microstructure coating employing axial suspension plasma spraying of the 28TaO2.5-18YO1.5-ZrO2 system and provide meaningful data regarding their thermal properties, SPS parameters and cyclic thermal performance benchmarking against 8 mol% YSZ.
