| 中文摘要: |
| 在纳米ZrO2中加入适量低熔点无机烧蚀材料SiO2和Cu，利用大气等离子喷(APS)技术，在TC4基体上制备出一种复合防热涂层。应用等离子火炬对涂层进行模拟烧蚀防热试验，运用X射线衍射（XRD）、扫描电镜（SEM）、电子探针（EPMA）等测试方法对粉末及涂层烧蚀前后的物相组成、显微结构和成分分布进行了观察和确定。研究结果表明，复合涂层表层烧蚀防热作用明显，内部仅出现液化现象，总体上涂层防热性能仍优于单一PYSZ涂层。涂层平均结合强度为47.7MPa。 |

| Nano-structure zirconia was doped with a certain amount of two kinds of inorganic ablative material, silica and copper. Then thermal protective composite coating was prepared on TC4-matrix by air plasma sprayed. Ablative thermal protection test was simulated by plasma torch . Phase, microstructure and distribution of compositon were charactered by some test means such as XRD, SEM and EMPA. The results show that ablative thermal protection occurred in evidence on the surface of composite coating, but liquidation only appeared inside coating. As a whole, thermal protection capability of composite coating is superior to that of single PYSZ coating. Average bond strength of composite coating is 47.7Mpa. |
