摘要

本研究通过前驱体浸润和热解（PIP）法制备了 BNf/SiBN 复合材料。研究了该复合材料在不同氧化温度下的抗氧化性，重点是裸纤维与受基体保护的纤维在不同氧化状态下的微观结构演变、相组成和氧化动力学。结果表明，BNf/SiBN 复合材料在 1100°C 的空气环境中保持稳定，而受基体保护的纤维即使在 1500°C 的环境中也能保持完整的结构。此外，我们还阐明了 SiBN 基体的氧化机制：SiBN 基体在高温下会先经历一个氧化阶段并转化为无定形的 SiO2 和 B2O3，从而阻碍氧气附着在纤维上，同时保持内部结构的完整性。耐超高温 BNf/SiBN 复合材料的出现以及对氧化行为的探索，为推动雷达天线罩材料的发展开辟了新的途径。

The antioxidative protection mechanism of the ultra-high temperature radome composite material BNf/SiBN

In the study, a BN_f/SiBN composite was fabricated through precursor infiltration and pyrolysis (PIP) method. The oxidation resistance of the composite was investigated at different oxidation temperatures, focusing on the micro-structure evolution, the phase composition and oxidation kinetics of bare fibers versus fibers protected by the matrix under various oxidation states. The result indicates that the BN_f/SiBN composite remains stable at 1100°C in air atmosphere, while the fibers protected by matrix maintain their complete structure even at 1500°C. Furthermore, we elucidated the oxidation mechanism of SiBN matrix: SiBN matrix undergoes a prior oxidation stage and transforms into amorphous SiO₂ and B₂O₃ at high temperatures to impede the oxygen attachment to fibers while preserving the integrity of internal structure. The emergence of ultra-high temperature resistant BN_f/SiBN composite and along with the exploration of oxidation behavior has opened up new approach for advancing radome material development.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
