摘要: Nanostructured thermal barrier coatings (nano-TBCs) are being extensively studied because of their excellent thermal barrier properties. The occurrence of sintering in TBCs is inevitable in service; however, accelerated sintering of the nano-TBCs may cause premature failure. This study focuses on the changes of microstructure and thermal conductivity of bimodal nano-TBCs during thermal exposure. Results show that there are two stages in the sintering process. It was found that the thermal conductivity increased rapidly in the first …
