| Abstract: |
| The development status of the five high temperature protection coating systems of refractory metals was reviewed, including intermetallic coatings generating protective oxidation films, noble metal coatings, alloy coatings generating protective oxidation films, inert oxide ceramic coatings and glass-ceramic based composite coatings. In this paper, their high-temperature protection mechanisms, preparation methods and failure mechanisms were reviewed. The traditional single high temperature protection coating systems have difficulty in meeting the performance requirements raised by new-generation orbit and attitude control rocket engines and hypersonic vehicles, such as oxidation resistance at ultra-high temperature, excellent resistance to thermal shock, good resistance to thermal erosion (ablation) and long service life. Based on this situation, some emerging and promising coating systems for ultra-high temperature protection as well as the corresponding coating preparation methods were proposed, such as transition metals like borides and carbides. The development of the ultra-high temperature protection coatings will give a great push to the development of modern aerospace industries. |
