ZrB2-SiC复相陶瓷涂层制备及其保护C/C-SiC复合材料性能
|
Abstract:
为提高C/C-SiC复合材料的超高温抗烧蚀性能，通过浆料涂刷和高温烧结相结合的方法在C/C-SiC复合材料表面制备了ZrB2-SiC复相陶瓷涂层，利用EDS、SEM对涂层的成分及微观形貌进行了分析。对涂层材料的力学性能和抗烧蚀性能进行了表征，结果表明：制备的ZrB2-SiC复相陶瓷涂层保护C/C-SiC复合材料的拉伸强度、弯曲强度及剪切强度分别为147 MPa、355 MPa和21.9 MPa，与无涂层保护的针刺C/C-SiC复合材料的力学性能相比略有下降。涂层材料具有良好的抗氧化烧蚀性能，经过热流密度为3 200 kW/m2的氧乙炔火焰烧蚀600 s试验，其线烧蚀率和质量烧蚀率分别为0.001 mm/s和0.0006 g/s。 A ZrB2-SiC ceramic coating was prepared on C/C-SiC composites by slurry painting and high temperature sintering to improve the ablation property of C/C-SiC composites at ultra high temperatures. The phase composition and microstructure of the ZrB2-SiC coating were analyzed by EDS and SEM. The mechanical and ablation properties of the coatings were investigated. The results show that the tensile strength, flexural strength and shear strength of the C/C-SiC composites protected by ZrB2-SiC coatings are 147 MPa, 355 MPa and 21.9 MPa, respectively. The mechanical properties of the coated C/C-SiC composites are little lower than the counterpart properties of the uncoated C/C-SiC composites. The coated C/C-SiC composite has an outstanding ablation property. After ablation by oxyacetylene torch test at a heat flux of 3 200 kW/m2 for 600 s, the coated sample has an average mass ablation rate of 0.001 mm/s and an average linear ablation rate of 0.0006 g/s.
