This paper gives a detailed survey about application of Thermal Barrier Coating(TBC)technology to aeroengines.First of all

thermal barrier coating system and coating technology are examined to identify the state of art of the coating technique

then characteristics of Plasma Spray Coating are compared with those of Electric Beam-Physic Vapor Deposition Coating.Meanwhile

the coating failure mechanism

coating interface strength and life prediction method are also surveyed.According to the thermal barrier coating researches at home and abroad

the authors offer some suggestions to promote the Chinese thermal barrier coating research and application.
