Abstract :

For increasing thermal efficiency and for lowering emissions requires gas turbine designers to further increase the combustion temperature that leads to the need for high temperature components such as combustion chambers, blades and vanes surfaces to face more rigorous conditions. Therefore, there is an urgent demand to develop new ceramic coatings with even lower thermal conductivity, higher stability and durability than currently used thermal barrier coatings coated on the surface of high temperature alloy components. In this presentation, we introduce new class of refractory ceramics as candidate materials for thermal barrier coatings, including the structure design, the rule of introducing defects in the crystal structure to further decrease the thermal conductivity, and to increase the structure stability at high temperature; the idea of suppressing the heat transfer at the high temperature by irradiation; the synthesis process and thermal properties. The mechanical properties at ambient and elevated temperature are also reported.
