中文摘要：

热障碍涂层(TBC ) 主要被用于先进汽轮机引擎的热部件绝缘从热气体的部件。热电导率上的 sintering 的效果和喷洒的常规血浆和 nanostructured 氧化钇的热障碍效果稳定了氧化锆(YSZ ) 热障碍涂层(TBC ) 被调查。热电导率的显著增加在热处理以后发生到两典型涂层。孔的变化只是反面。增加更急速地与常规血浆的相比与退火预定的 nanostructured 氧化锆涂层的谷物尺寸喷洒了涂层，它显示涂层 sintering 比常规涂层的做更多的贡献到 nanostructured 涂层的热传导性。用温度差别技术的热障碍效果测试在两涂层上被执行。在热处理和衰落在低热传导性范围似乎更激烈以后，热障碍效果随热电导率的增加减少。在热障碍效果的衰落是大约 80 駜吗？？

英文摘要：

Thermal barrier coatings （TBCs） are mostly applied to hot components of advanced turbine engines to insulate the compo- nents from hot gas. The effect of sintering on thermal conductivity and thermal barrier effects of conventional plasma sprayed and nanostructured yttria stabilized zirconia （YSZ） thermal barrier coatings （TBCs） are investigated. Remarkable increase in thermal conductivity occurs to both typical coatings after heat treatment, The change of porosity is just the opposite. The grain size of the nanostructured zirconia coating increases more drastically with annealing time compared to that of the conventional plasma sprayed coating, which indicates that coating sintering makes more contributions to the thermal conductivity of the nanostructured coating than that of the conventional coating. Thermal barrier effect tests using temperature difference technique are performed on both coatings. The thermal barrier effects decrease with the increase of thermal conductivity after heat treat- ment and the decline seems more drastic in low thermal conductivity range. The decline in thermal barrier effects is about 80℃ for nanostructured coating after 100 h heat treatment, while the conventional coating reduces by less than 60 ℃ compared to the as-sprayed coating.
