Outline of Final Research Achievements |
A method was newly developed for measuring the thermal conductivity and interfacial thermal resistance of thermal barrier coatings (TBCs), which consist of metallic bond coats (BCs) and ceramic top coats (TCs) on superalloys. The effect of the heat treatment on the interfacial thermal resistance was investigated. It was found that the interfacial thermal resistance depends on the heat treatment. The interfacial thermal resistance decreases with the development of the thermally grown oxide by the heat treatment in air. Furthermore, the TCs by plasma sprayings found to have significantly anisotropic thermal diffusivity.
