307 大気プラズマ溶射遮熱コーティングの機械的特性とスプラット組織構造との関連性(OS2-2 皮膜・薄膜の機械的特性,OS2 薄膜・皮膜とその膜構造の特性評価)
詳細
The correlation between the mechanical properties and the splat microstructure of an APSed TBC was studied by using the simple sintering model and the numerical simulation, i.e., the distinct element method. It was cleared from results of the numerical simulation that the mechanical properties of an APSed TBC were controlled with the change of the splat structure by the initial stage of the sintering. The change of mechanical properties in the APSed TBCs by the thermal exposure is predictable by using the proposed method in this work.
