Thermal barrier coatings (TBCs) are the key technologies for hot-components in advanced gas turbine and land-based engines. Yttria stalized zirconia (YSZ) is now extensively used as ceramic topcoat in TBC system. However, YSZ cannot be used for next generation aircraft engines due to its limitation in high-temperature capabilities and thermal barrier performances. In this paper, recent research progress of several novel TBC ceramic candidates covering multiple oxide co-doped zirconia, A2B2O7-type compounds, magnetoplumbite compounds, garnet-type compounds, perovskites and other new oxides ceramics is overviewed. And the development tendencies and challenges of ultra-high temperature TBC materials for future applications are prospected.
