| Abstract: | The theory of thermal conduction of ceramic materials and thermal conductivities of current thermal barrier coatings were reviewed to increase further thermal insulation of plasma sprayed thermal barrier coatings.The methods of increasing thermal insulation of plasma sprayed thermal barrier coatings including seeking for alternative ceramic materials,addition of some dopants,preparing nanostructured coating and double-ceramic-layer coating were proposed.It is indicated that the combination of colouring plus nanostructured and double-ceramic-layer coatings with lower thermal conductivity is an very important research direction in future. |
