| 2 | Increasing the Tensile Property of Unidirectional Carbon/Carbon Composites by Grafting Carbon Nanotubes onto Carbon Fibers by Electrophoretic Deposition显示文摘Although in-situ growing carbon nanotubes(CNTs) on carbon fibers could greatly increase the matrix-dominated mechanical properties of carbon/carbon composites(C/Cs),it always decreased the tensile strength of carbon fibers.In this work,CNTs were introduced into unidirectional carbon fiber(CF) preforms by electrophoretic deposition(EPD) and they were used to reinforce C/Cs.Effects of the content of CNTs introduced by EPD on tensile property of unidirectional C/Cs were investigated.Results demonstrated that EPD could be used as a simple and efficient method to fabricate carbon nanotube reinforced C/Cs(CNT—C/Cs) with excellent tensile strength,which pays a meaningful way to maximize the global performance of CNT—C/Cs. | Qiang Song Kezhi Li Hejun Li Qiangang Fu | 2013 | Journal of Materials Science & Technology2013，29，8： | 9 |
| 3 | Advances in ultra-high temperature ceramics,composites,and coatings显示文摘Ultra-high temperature ceramics(UHTCs)are generally referred to the carbides,nitrides,and borides of the transition metals,with the Group IVB compounds(Zr&Hf)and TaC as the main focus.The UHTCs are endowed with ultra-high melting points,excellent mechanical properties,and ablation resistance at elevated temperatures.These unique combinations of properties make them promising materials for extremely environmental structural applications in rocket and hypersonic vehicles,particularly nozzles,leading edges,and engine components,etc.In addition to bulk UHTCs,UHTC coatings and fiber reinforced UHTC composites are extensively developed and applied to avoid the intrinsic brittleness and poor thermal shock resistance of bulk ceramics.Recently,high-entropy UHTCs are developed rapidly and attract a lot of attention as an emerging direction for ultra-high temperature materials.This review presents the state of the art of processing approaches,microstructure design and properties of UHTCs from bulk materials to composites and coatings,as well as the future directions. | Dewei NI Yuan CHENG Jiaping ZHANG Ji-Xuan LIU Ji ZOU Bowen CHEN Haoyang WU Hejun LI Shaoming DONG Jiecai HAN Xinghong ZHANG Qiangang FU Guo-Jun ZHANG | 2022 | Journal of Advanced Ceramics2022，11，1： | 9 |
| 4 | Micro/nano multiscale reinforcing strategies toward extreme high-temperature applications:Take carbon/carbon composites and their coatings as the examples显示文摘Carbon fiber reinforced carbon composites(C/Cs),are the most promising high-temperature materials and could be widely applied in aerospace and nucleation fields,owing to their superior performances.However,C/Cs are very susceptible to destructive oxidation and thus fail at elevated temperatures.Though matrix modification and coating technologies with Si-based and ultra-high temperature ceramics(UHTCs)are valid to enhance the oxidation/ablation resistance of C/Cs,it’s not sufficient to satisfy the increasing practical applications,due to the inherent brittleness of ceramics,mismatch issues between coatings and C/C substrates,and the fact that carbonaceous matrices are easily prone to high-temperature oxidation.To effectively solve the aforementioned problems,micro/nano multiscale reinforcing strategies have been developed for C/Cs and/or the coatings over the past two decades,to fabricate C/Cs with high strength and excellent high-temperature stability.This review is to systematically summarize the most recent major and important advancements in some micro/nano multiscale strategies,including nanoparticles,nanowires,carbon nanotubes/fibers,whiskers,graphene,ceramic fibers and hybrid micro/nano structures,for C/Cs and/or the coatings,to achieve high-temperature oxidation/ablation-resistant C/Cs.Finally,this review is concluded with an outlook of major unsolved problems,challenges to be met and future research advice for C/Cs with excellent comprehensive mechanical-thermal performance.It’s hoped that a better understanding of this review will be of high scientific and industrial interest,since it provides unusual and feasible new ideas to develop potential and practical C/Cs with improved high-temperature mechanical and oxidation/ablation-resistant properties. | Qiangang Fu Pei Zhang Lei Zhuang Lei Zhou Jiaping Zhang Jie Wang Xianghui Hou Ralf Riedel Hejun Li | 2022 | Journal of Materials Science & Technology2022，，1： | 7 |
| 5 | Microstructure and flexural properties of carbon/carbon composite with in-situ grown carbon nanotube as secondary reinforcement显示文摘Carbon nanotubes (CNTs) were in-situ grown in carbon felts using ferric chloride as catalyst and natural gas as carbon precursor via thermal gradient chemical vapor infiltration (TGCVI). Subsequently, the carbon felts were densified to obtain CNT reinforced carbon/carbon (C/C) composites in the same furnace. Effects of CNTs on the microstructure and flexural property of C/C composites were investigated by polarized light microscopy, Raman spectroscopy, scanning electron microscopy and universal mechanical testing machine. The results of PLM observation and Raman analysis showed that CNTs have two-sided effects on the microstructure of pyrocarbon: the pyrocarbons in the region without CNTs show medium texture; while, in the region full of CNTs, the microstructure was low-textured or even isotropic though the TGCVD conditions would lead to the deposition of pure low texture pyrocarbons. Analysis based on stress-strain curves demonstrated that the flexural strength increased first and then decreased with the CNT content increasing. When the CNT content was 5.23 wt%, the flexural strength was maximum and had a nearly 35% improvement compared with pure C/C composite. Besides, after adding CNTs, the flexural modulus of the composites decreased and the ductility increased obviously, indicating CNTs can toughen C/C composites. | Hai Zhang Lingjun Guo Qiang Song Qiangang Fu Hejun Li Kezhi Li | 2013 | Progress in Natural Science:Materials International2013，23，2： | 6 |
| 6 | Ablative and Mechanical Properties of C/C—ZrC Composites Prepared by Precursor Infiltration and Pyrolysis Process显示文摘C/C-ZrC composites with continuous ZrC matrix were prepared by precursor infiltration and pyrolysis process using zirconium-containing polymer.Ablation properties of the composites were investigated by oxyacetylene flame with heat flux of 2380 and 4180 kW/m^2,respectively.The results showed that C/C-ZrC composites exhibited excellent ablation resistance under the heat flux of 2380 kW/m^2 for 120 s and a tree-coral-like ZrO_2protective layer formed after ablation.However,when the heat flux increased to 4180 kW/m^2,the maximum temperature of ablated surface reached 2500 ℃ and a strong degradation of ablation resistance was observed due to the weak bonding between the formed ZrO_2 layer and the composites.The flexural strength of C/C-ZrC composites was 110.7 ± 7.5 MPa.There were a large number of carbon fiber bundles pull-out,and the composites exhibited a pseudo-plastic fracture behavior. | Kezhi Li Jing Xie Hejun Li Qiangang Fu | 2015 | Journal of Materials Science & Technology2015，31，1： | 5 |
| 7 | Molten salt synthesis, formation mechanism, and oxidation behavior of nanocrystalline HfB2 powders显示文摘Nanocrystalline Hf B2 powders were successfully synthesized by molten salt synthesis technique at 1373 K using B and Hf O2 as precursors within KCl/Na Cl molten salts.The results showed that the as-synthesized powders exhibited an irregular polyhedral morphology with the average particle size of 155 nm and possessed a single-crystalline structure.From a fundamental aspect,we demonstrated the molten-salt assisted formation mechanism that the molten salts could accelerate the diffusion rate of the reactants and improve the chemical reaction rate of the reactants in the system to induce the synthesis of the high-purity nanocrystalline powders.Thermogravimetric analysis showed that the oxidation of the as-synthesized Hf B2 powders at 773–1073 K in air was the weight gain process and the corresponding oxidation behavior followed parabolic kinetics governed by the diffusion of oxygen in the oxide layer. | Da LIU Qiangang FU Yanhui CHU | 2020 | Journal of Advanced Ceramics2020，9，1： | 4 |
| 8 | Mullite Oxidation Resistant Coating for SiC-coated Carbon/Carbon Composites by Supersonic Plasma Spraying显示文摘To improve the oxidation resistance of carbon/carbon (C/C) composites, mullite coating was prepared on the surface of SiC-coated C/C composites by supersonic plasma spraying. Phases and microstructures of mullite coating were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The coating primarily consists of a single phase of mullite (3Al2O3-2SiO2). The SEM results show that mullite coating was continuous and well bonded with the SiC inner layer without penetrating crack. Mullite coating exhibited good oxidation resistance. After 98.5 h oxidation at 1773 K and 9 thermal shock cycles between 1773 K and room temperature, the weight loss of the coated C/C composites was only 2.57%. | Chao Ma Hejun Li Heng Wu Qiangang Fu Can Sun Xiaohong Shi Yulei Zhang Zhengzhong Zhang Jun Tao Zhihai Han | 2013 | Journal of Materials Science & Technology2013，29，1： | 4 |
| 9 | SiC-Si-ZrSiO_4 Multiphase Oxidation Protective Coating for Carbon/Carbon Composites显示文摘In order to improve the anti-oxidation property of carbon/carbon (C/C) composites,a novel SiC-Si-ZrSiO_4 multiphase oxidation protective coating was produced on the surface of C/SiC coated carbon/carbon compos- ites by a pack cementation technique.The phase composition and microstructure of the as-prepared coatings were characterized by XRD (X-ray diffraction),SEM (scanning electron microscopy) and EDS (energy dis- persive spectroscopy).Oxidation behavior of the multiphase coated C/C composites was also investigated. It showed that the as-prepared coating characterized by excellent oxidation resistance and thermal shock re- sistance could effectively protect C/C composites from oxidation at 1773 K for 57 h in air and endure the thermal cycle between 1773 K and room temperature for 12 times,whereas the corresponding weight loss is only 1.47%.The excellent oxidation protective ability of the SiC-Si-ZrSiO_4 coating could be attributed to the C/SiC gradient inner layer and the multiphase microstructure of the coating. | Yulei ZHANG Hejun LI Qiangang FU Kezhi LI Dangshe HOU | 2008 | Journal of Materials Science & Technology2008，24，6： | 4 |
| 10 | SiC Nanowires Toughed HfC Ablative Coating for C/C Composites显示文摘In order to improve ablation resistance of carbon/carbon(C/C) composites,SiC nanowires were prepared on C/C composites surface in prior through chemical vapor reaction before HfC coating.SiC nanowires grew randomly and had good combination with HfC coating.SiC nanowires toughed HfC coating had lower linear and mass ablation rates than original HfC coating.The surface was much flatter and exhibited smaller cracks in center region.The ablation mechanism of HfC coating has been changed by SiC nanowires.Thicker HfO2 fused layer was formed on the surface of the toughed HfC coating,which could provide efficient protection for C/C composites.Therefore,SiC nanowires toughed HfC coating behaved in better ablation resistance. | Hejun Li Yongjie Wang Qiangang Fu Yanhui Chu | 2015 | Journal of Materials Science & Technology2015，31，1： | 4 |
| 11 | Ablative Property of C/C–SiC–HfC Composites Prepared via Precursor Infiltration and Pyrolysis under 3,000 °C Oxyacetylene Torch显示文摘C/C–SiC–HfC composites were fabricated via precursor infiltration and pyrolysis using a mixture solution of organic hafnium-containing polymer and polycarbosilane as precursor. The microstructures and the phases of the composites were analyzed by scanning electron microscopy and X-ray diffraction. The ablation resistance of the composites was evaluated under 3,000 °C oxyacetylene torch. After ablation for 120 s, the composites exhibit good ablation properties with the linear and mass ablation rates of 9.1 9 10-4mm/s and 1.30 9 10-3g/s, which are far lower than those of the C/C–SiC composites. The excellent ablative property of the C/C–SiC–HfC composites is resulted from the formation of HfO2 molten layer on the surface of the composites, which could play a positive role in reducing heat transfer and preventing oxygen transport to the underlying carbon substrate. | Min Yan Hejun Li Qiangang Fu Jing Xie Lei Liu Bo Feng | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，6： | 4 |
| 12 | W-Mo-Si/SiC Oxidation Protective Coating for Carbon/Carbon Composites显示文摘W-Mo-Si/SiC 双层氧化防护涂层 forcarbon/carbon ( C/C ) composites 被二拍子的圆舞包装硬化 technique.XRD ( X-raydiffraction )准备, SEM (扫描电子显微镜学)结果涂层由第一步包装硬化获得了的表演是薄内部缓冲区层原文如此与一些裂缝和毛孔,并且一个新阶段(W_xMo_( 1-x )) Si2 出现在第二步包装硬化以后。氧化测试显示出那,在在在为 175 h 并且在在 18 次的 1773 K 和房间温度之间的热骑车的 1773 K 的空中的氧化以后, W-Mo-Si/SiC 涂的 C/C composites 的重量损失仅仅是2.06% .Theoxidation W-Mo-Si/SiC 涂层的保护的失败在涂层被归因于一些可穿透的裂缝的形成。 | Dangshe HOU Kezhi LI Hejun LI Qiangang FU Jian WEI Yulei ZHANG | 2007 | Journal of Materials Science & Technology2007，23，4： | 3 |
| 13 | SiC/Si-W-Mo coating for protection of C/C composites at 1873 K显示文摘In order to prevent carbon/carbon composites from oxidation at 1873 K, an efficient oxidation protective SiC/Si-W-Mo coating was prepared by a two-step pack cementation technique. The microstructures and the phase composition of the as-received multi-coating were examined by scanning electron microscopy (SEM) and X-ray diffraction (XRD). It is seen that the compact multi-coating is composed of α-SiC, Si, and (WxMo1-x)Si2. Oxidation test shows that, after oxidation at 1873 K in air for 102 h and thermal cycling between 1873 K and room temperature for 10 times, the weight loss of the SiC/Si-W-Mo coated C/C composites is only 0.26%. The invalidation of the multi-coating is attributed to the formation of penetrable cracks in the coating. | Dangshe Hou Kezhi Li Hejun Li Qiangang Fu Yulei Zhang | 2008 | Journal of University of Science and Technology Beijing2008，15，6： | 3 |
| 14 | Microstructure and oxidation resistance of SiC–MoSi_2 multi-phase coating for SiC coated C/C composites显示文摘In order to improve the anti-oxidation of C/C composites, a SiC–MoSi2multi-phase coating for SiC coated carbon/carbon composites(C/C)was prepared by low pressure chemical vapor deposition(LPCVD) using methyltrichlorosilane(MTS) as precursor, combined with slurry painting from MoSi2 powder. The phase composition and morphology were analyzed by scanning electron microscope(SEM) and X-ray diffraction(XRD) methods, and the deposition mechanism was discussed. The isothermal oxidation and thermal shock resistance were investigated in a furnace containing air environment at 1500 1C. The results show that the as-prepared SiC–MoSi2coating consists of MoSi2 particles as a dispersing phase and CVD–SiC as a continuous phase. The weight loss of the coated samples is 1.51% after oxidation at 1500 1C for 90 h, and 4.79% after 30 thermal cycles between 1500 1C and room temperature. The penetrable cracks and cavities in the coating served as the diffusion channel of oxygen, resulted in the oxidation of C/C composites, and led to the weight loss in oxidation. | Zibo He Hejun Li Xiaohong Shi Qiangang Fu Heng Wu | 2014 | Progress in Natural Science:Materials International2014，24，3： | 2 |
| 15 | A Multi-interlayer LMAS Joint of C/C-SiC Composites and LAS Glass Ceramics显示文摘Porous C/C-SiC composites were prepared through a two-step chemical vapor infiltration process,and a multi-interlayer joint of Li20-MgO-Al_2O_3-SiO_2(LMAS) was applied to join C/C-SiC composites and lithium aluminum silicate(LAS) glass ceramics by means of a vacuum hot-pressing technique.Plenty of SiC whiskers were generated in the pores of low-density C/C composites during chemical vapor deposition process,which is essentia! to form a zigzag interface structure between C/C-SiC substrate and the LMAS interlayer.The average shear strength of the LMAS joint was improved from 12.17 to 19.91 MPa after changing the composites from high-density C/C composites(1.75 g/cm^3) with a CVD-SiC coating to the C/C-SiC composites with a low density(1.48 g/cm^3).The improvement of the joint strength is mainly attributed to the formation of the inlay structure at the SiC-C/C and SiC-LMAS interfaces. | Qiangang Fu Fengling Zhao Hejun Li Han Peng Xiaoying Nan | 2015 | Journal of Materials Science & Technology2015，31，5： | 2 |
| 16 | Si-Al-Ir Oxidation Resistant Coating for Carbon/Carbon Composites by Slurry Dipping显示文摘A Si-Al-Ir oxidation resistant coating was prepared for SiC coated carbon/carbon composites by slurry dipping. The phase composition, microstructure and oxidation resistance of the as-prepared Si-Al-Ir coating were studied by XRD (X-ray diffraction), SEM (scanning electron microscopy), and isothermal oxidation test at 1773 K in air, respectively. The surface of the as-prepared Si-Al-Ir coating was dense and the thickness was approximately 100 μm. Its anti-oxidation property was superior to that of the inner SiC coating. The weight loss of SiC/Si-Al-Ir coated carbon/carbon composites was less than 5 wt. pct after oxidation at 1773 K in air for 79 h. The local oxidation defects in the coating may result in the failure of the SiC/Si-Al-Ir coating. | Min Huang Kezhi Li Hejun Li Qiangang Fu Yu Wang | 2009 | Journal of Materials Science & Technology2009，25，3： | 2 |
| 17 | Effect of Monolithic LaB_6 on the Ablation Resistance of ZrC/SiC Coating Prepared by Supersonic Plasma Spraying for C/C Composites显示文摘Ablation resistance of monolithic LaB_6-doped ZrC coating for SiC-coated carbon/carbon composites by supersonic atmospheric plasma spray was investigated under an oxyacetylene torch with a heat flux of 4.18 MW/m^2. Result shows that ZrC coating with 10 vol.% LaB_6 has a good ablation resistance compared with pure ZrC, ZrC with 20 vol.% LaB_6 and SiC-doped ZrC coating. After ablation for 15 s, the weight is increased by 1.12 mg/s. The good ablation resistance is ascribed to the formation of a stabilized scale which consists of protective La_2Zr_2O_7-containing molten phase and ZrO_2 particles keeping the integrity of the coating. | Yujun Jia Hejun Li Lu Li Qiangang Fu Kezhi Li | 2016 | Journal of Materials Science & Technology2016，32，10： | 2 |
