| 摘 要： | 针对铌及铌合金高温下抗氧化性能差的现象，进行了高温抗氧化防护涂层的设计。采用料浆熔烧法在C-103铌合金表面制备改性的Si—Mo涂层，并对改性的Si-Mo涂层的形貌、结构、成分及1700℃的抗氧化性能进行了分析。结果表明，涂层与基体之间通过扩散形成过渡层，达到了冶金结合，涂层的复合结构有利于提高抗氧化性能。在氧化环境下，涂层表面生成一层玻璃层，阻止氧的进一步扩散。试样在1700℃下氧化3～4h后，涂层元素与基体发生互扩散，在界面处形成大量集中孔洞，使涂层从其主体与过渡层接触的界面处发生断裂，导致涂层失效。

| Abstract: | The high-temperature oxidation-resistant coating was designed for improving the oxidation resistance properties of niobium and nb-base alloy.By slurry firing,the high-temperature oxidation-resistant coating was prepared on niobium C-103 alloy.The structure,composition and phase distribution of the coating and the relationship between these features and the oxidation resistant of the coating were investigated by SEM,EDS and XRD.The results indicate that a transitional layer between the coating and the subtra... |
