The paper introduced the main materials systems and structure characterstics of Graded Thermal Barrier Coatings ( TBCs ). Current status of preparation techniques, evaluation methods, study on failure mechanism and structure optimizing for TBCs were reviewed. Several possible hotspots and developing trends about TBCs in the future were put forward.
