文摘 航空发动机中的碳化硅纤维增强碳化硅陶瓷基复合材料(SiC_f/SiC)因承受高温高速燃烧气体的氧化腐蚀而发生损伤甚至失效。本工作利用燃气发生装置模拟航空发动机中复杂燃气环境,将以一定比例混合后的航空煤油与液氧燃料点燃,形成高温高速燃烧气体对材料进行考核。对SiC_f/SiC复合材料分别进行1200 ℃燃气环境10 h氧化实验和1000次热冲击实验,探究环境屏障涂层(environmental barrier coating,EBC)对SiC_f/SiC复合材料的防护作用。对燃气环境考核后的SiC_f/SiC复合材料和SiC_f/SiC-EBC复合材料进行单轴拉伸强度测试,并利用扫描电镜对其断口及截面微观形貌进行观察。结果表明:在燃气环境下氧化10 h后,SiC_f/SiC复合材料和SiC_f/SiC-EBC复合材料内部没有发生明显的界面层及纤维氧化,单轴拉伸强度下降不到2%;在燃气环境下经过1000次热冲击后,在SiC_f/SiC复合材料内部形成多处微裂纹并发生了界面层的氧化腐蚀,单轴拉伸强度下降41.3%; EBC涂层可以有效保护SiC_f/SiC复合材料免受高温燃气的氧化腐蚀, SiC_f/SiC-EBC复合材料在经过1000次热冲击后的单轴拉伸强度下降16.6%。
其他语种文摘 Silicon carbide fiber-reinforced silicon carbide ceramic matrix composites(SiC_f/SiC) used in aero-engines are damaged or even failed due to the oxidation and corrosion by high-temperature and high-speed combustion gases. In this work, the gas generation device was used to simulate the complex gas environment in the aircraft engine, and the aviation kerosene mixed with liquid oxygen fuel in a certain proportion was ignited to form a high-temperature and high-speed combustion gas to assess the material. The oxidation test for 10 h and thermal shock test for 1000 cycles in combustion gas environment at 1200 ℃ were conducted on SiC_f/SiC composites respectively. And the protective effect of environmental barrier coating(EBC) on SiC_f/SiC composites was investigated. Uniaxial tensile tests were conducted on SiC_f/SiC composites and SiC_f/SiC-EBC composites after combustion gas environment assessment, and their fracture and cross-section micro-morphologies were observed by scanning electron microscopy. The results show that no significant oxidation of fibers and interphases is found in SiC_f/SiC composites and SiC_f/SiC-EBC composites after oxidation for 10 h in combustion gas environment,and their uniaxial tensile strength decreases by less than 2%. After 1000 thermal shock cycles in combustion gas environment, multiple micro-cracks are formed and oxidative corrosion of the interfacial layer occurs inside the SiC_f/SiC composites, and the uniaxial tensile strength decreases by 41.3%. The EBC coating can effectively protect the SiC_f/SiC composites from oxidation and corrosion of high-temperature gas,and the uniaxial tensile strength of SiC_f/SiC-EBC composites decreases by 16.6% after 1000 thermal shock cycles.
