In this work, La$_2$Mo$_2$O$_9$ (LMO) powder was synthesized via the molten salt procedure. The coatings of NiCrAlY/LMO, NiCrAlY/YSZ and NiCrAlY/YSZ/LMO were developed by the plasma-spray process. The NiCrAlY/LMO coating demonstrated higher oxidation and hot corrosion rates than those of NiCrAlY/YSZ and NiCrAlY/YSZ/LMO coatings. The higher oxidation and hot corrosion rates are attributed to higher ionic conductivity of LMO in the NiCrAlY/LMO coating. The NiCrAlY/YSZ/LMO coating demonstrated the lowest oxidation and hot corrosion rates, while NiCrAlY/YSZ coating exhibited an intermediate behaviour. Further, the coating also showed higher thermal gradientperformance. The high oxidation, hot corrosion resistance and thermal gradient performance achieved due to the suppression of ionic conductivity by YSZ buffer layer in the multi-layer coating. The present work paves new pathways for the development of plasma spray coatings with low thermal conductivity oxides for the rapid heating application of thermal barrier coatings.
