Abstract
The effects of La2O3 and HfO2 addition on thermal conductivity and thermal cycle life of EB-PVD YSZ coatings were investigated. La2O3 and HfO2 were selected as additives, because they significantly suppress the sintering of YSZ. The developed coating showed low thermal conductivity as well as high resistance to sintering. Burner rig tests confirmed that the developed coating have a superior thermal insulating effect and have a longer life than that of a coating with conventional composition.
