| Abstract: | Thermal shock resistance, oxidation resistance and mechanical performances of the gradient thermal barrier coatings are reviewed. The principles of selection and design of the materials for surface layer, bottom layer and gradient transition layer are given. The failure mechanism of them is explored. Some problems are also presented for further investigation. |
