摘要:
以MoSi2和TaSi2为辐射剂、硼硅酸盐玻璃为黏结剂、SiB6为烧结助剂,采用料浆浸渍结合高温快速热处理法在纤维状ZrO2陶瓷表面制备梯度多孔硅化物-玻璃涂层。通过X线衍射仪(XRD)表征涂层表面物相组成; 采用扫描电子显微镜(SEM)和激光共聚焦显微镜(CLSM)表征涂层的微观形貌。测试硅化物-玻璃涂层的抗热震性能和辐射性能。结果表明:涂层呈现出表面密实和内部多孔的梯度多孔涂层结构。在1 500 ℃到室温抗热震循环10次后,涂层表面无裂纹,比多孔结构涂层具有更优异的抗热震性能。硅化物-玻璃涂层在0.3~2.5 μm波段室温发射率达0.85。
Abstract:
A gradient porous MoSi2-TaSi2-glass coating was designed and prepared on fibrous ZrO2 ceramic via slurry dipping and subsequent high temperature rapid sintering with MoSi2 and TaSi2 as the emissive agents,borosilicate glass as the binder and SiB6 as the sinter additive.The surface phase composition and the microstructures of the coatings were characterized by X-ray diffraction(XRD),scanning electron microscope(SEM)and confocal laser scanning microscope(CLSM).The radiative property and thermal shock behavior of the coating had been investigated.Results showed that the coating presented a dense top layer and a porous inner layer.No micro cracks were generated on the surface of the coating after 10 thermal shock cycles between 1 500 ℃ and room temperature,which presented better thermal shock resistance than that of porous coating.The total emissivity of the coating was above 0.85 in the range of 0.3-2.5 μm at room temperature.
