Abstract

Two structural designs are based on the arapaima fish scale structure to enhance the performance of composites. A double-layer SiC/PyC coating was deposited to modify C/C-HfC-SiC composites by chemical vapor deposition. The introduction of PyC coating reduced the porosity and roughness of composites. Ar-O₂-Al₂O₃ plasma ablation system was used to assess the composites. The composites with arapaima fish scale structure showed good flexural and ultra-temperature particle erosion resistance. The samples with the introduction of PyC layer showed higher flexural strength of 220 MPa, which is 40.13 % higher than that of without. After ablation 40 s, the linear ablation rates decreased from 5.95 μm/s to −4.6 μm/s. This study provides new ideas to develop C/C composites with improved ablation-resistant and mechanical properties.

具有防弹层的 C/C-HfC-SiC 复合材料的抗烧蚀性和机械性能

两种结构设计均基于rapaima鱼鳞结构，以提高复合材料的性能。通过化学气相沉积法沉积了双层 SiC/PyC 涂层，以改性 C/C-HfC-SiC 复合材料。PyC 涂层的引入降低了复合材料的孔隙率和粗糙度。使用 Ar-O2-Al2O3 等离子烧蚀系统对复合材料进行评估。具有鱼鳞结构的复合材料显示出良好的抗弯曲性和超高温颗粒侵蚀性。引入 PyC 层的样品的抗弯强度达到 220 兆帕，比未引入 PyC 层的样品高出 40.13%。烧蚀 40 秒后，线性烧蚀率从 5.95 μm/s 降至 -4.6 μm/s。这项研究为开发具有更好耐烧蚀性和机械性能的 C/C 复合材料提供了新思路。

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.
