Some aspects of thermal barrier coatings (TBC) are reviewed. TBCs are composed of a surface ceramic coating and an intermediate metallic bond layer,and are coated on superalloys to improve its high temperature performances. The coatings are usually made by APS plasma spray or EBPVD (electron beamphysical vapour deposition) Methods. Finally, the failure Mechanisms of TBCs are discussed.
