Review on plasma sprayed oxidation resistant coatings for C/C composites
Shaanxi Key Laboratory of Fiber Reinforced Light-Weight Composites, Northwestern Polytechnical University, Xi’an 710072, China
Oxidation sensitivity is a critical obstacle to the rapid development of carbon/carbon(C/C) composites as the thermal structural materials in aerospace applications. Currently, surface coating technology is the most effective method to achieve the long-term stable service of C/C composites in high temperature oxygen-containing environments. Among them, plasma spraying technology, which has been widely used in the preparation of thermal barrier coatings for aero-engines, has attracted much attention. In this paper, starting from the plasma sprayed high-temperature oxidation resistant coatings for C/C composites, domestic and international research progress of boride, silicide and oxide based oxidation resistant coatings have been reviewed, the protective properties based on different spraying technologies, composition/structure designs and service conditions have been compared and summarized, and the prospect future for subsequent research in this field has been proposed.
氧化敏感性是限制碳/碳(C/C)复合材料作为超高温结构材料应用于航空航天领域的关键瓶颈。表面涂层技术是目前在高温含氧环境下有望实现C/C复合材料长时稳定服役的最有效手段。其中, 广泛应用于制备航空发动机热防护涂层的等离子喷涂技术备受关注。从C/C复合材料表面等离子喷涂高温抗氧化涂层体系出发, 综述了硼化物、硅化物和氧化物基抗氧化涂层的国内外研究进展, 基于不同喷涂工艺、成分/结构设计和测试环境下的防护性能进行了对比总结, 并对后续该方向研究提出了展望。
