Abstract:The research and application of TBCs for aeroengine and gas turbine blades were introduced. The present situation and de? velopment trend of TBCs adhesive layer and ceramic layer were reviewed in terms of material，fabrication，application and main failure rea? sons. MCrAlY，which was widely used as binder，and PtAl，which was emerging in recent years，were introduced in detail. The ceramic lay? er materials，including multiple rare earth oxides doped with ZrO2，fluorite structure compounds and rare earth zirconates，were introduced in detail. Plasma spraying and electron beam physical vapor deposition，which were widely used in production，were introduced in detail. The application of TBCs in China was emphatically introduced. The failure reasons of the TBCs were mainly analyzed from TGO and CMAS. Finally，it is briefly discussed that the development direction will be more than 1300 ℃ ultra-high temperature ceramic layer，more than 1200 ℃ oxidation resistant metal bonding layer and match well with advanced single crystal superalloy interface，long life and good CMAS resistance.
