| Abstract: | This paper reviews briefly the development of various thermal barrier coating (TBC) systems and discusses theories about heat transfer within zirconia based ceramics,including the influence of coating microstructure,ceramic composition and so on. The methods to decrease the thermal conductivity of ceramic coatings and guidelines to develop alternative materials for thermal barrier coatings at higher temperature are shown. Moreover,the status of study on TBCs with lower thermal conductivity is introduced in detail. |
