“…With SiO 2 playing as a bonding agent, oxygen cannot easily diffuse inward through the continuous oxide layer, protecting the C f /SiBCN composites against further oxidation. Moreover, the liquid SiO 2 can spread into the pores and defects of the composites to protect the inward composites . In contrast, at relatively high temperature and low oxygen partial pressure, active oxidation occurs and formation of SiO(g) is more favorable, which is detrimental for the ablation resistance of the material …”

In this work, Cf/SiBCN composites are fabricated by an improved precursor infiltration and pyrolysis (PIP) approach. Ablation behavior of the Cf/SiBCN composites is investigated in plasma ablation flame at a heat flux of 4.02 MW m−2, which provides a quasi‐real hypersonic service environment at a temperature up to 2200°C. After ablation, the ablated surface is covered with oxidation products in the form of oxide layer, fibrous residues, or bubbles, which effectively isolates the sample surface from the plasma flame and inhibits the scouring of high‐speed flame to the composites. As a result, the Cf/SiBCN composites present an excellent ablation‐resistant property, with linear and mass recession rates as low as 0.0030 mm s−1 and 0.0539 mg mm−2 s−1, respectively. It is also revealed that the material at ablation center undergoes crystallization and oxidation processes during ablation, while the ablation behavior at transition area and ablation fringe only contains oxidation process due to the local temperature difference. Si3N4 and SiC grains are precipitated from amorphous SiBCN matrix during the crystallization process, and the oxidation process mainly involves the oxidation of carbon fiber and SiBCN matrix, etc.

“…The most promising material at present is SiC and SiC-based materials, which allow to obtain the specified combination of properties: high specific strength and rigidity; heat resistance; wear resistance; high thermal conductivity and heat-shielding properties; radiation strength [88]; etc. ; thermal conductivity of 180-200 W/(m • K) (as in Al), in single crystals up to 470 W/ (m • K); working temperaturemore than 1350°C (as in heatresistant steels); melting/decomposing point is 2830°C; resistance in the oxidizing and reducing environment is higher than that of Ti [89]. PB-AM technologies demonstrate significant potential in manufacturing of composite materials both from the blended powders and pre-agglomerated powders where each grain already contains multiple materials sintered together [28,38,39,90].…”

Powder-bed additive manufacturing for aerospace application: Techniques, metallic and metal/ceramic composite materials and trends

The current paper is devoted to classification of powder-bed additive manufacturing (PB-AM) techniques and description of specific features, advantages and limitation of different PB-AM techniques in aerospace applications. The common principle of “powder-bed” means that the used feedstock material is a powder, which forms “bed-like” platform of homogeneous layer that is fused according to cross-section of the manufactured object. After that, a new powder layer is distributed with the same thickness and the “printing” process continues. This approach is used in selective laser sintering/melting process, electron beam melting, and binder jetting printing. Additionally, relevant issues related to powder raw materials (metals, ceramics, multi-material composites, etc.) and their impact on the properties of as-manufactured components are discussed. Special attention is paid to discussion on additive manufacturing (AM) of aerospace critical parts made of Titanium alloys, Nickel-based superalloys, metal matrix composites (MMCs), ceramic matrix composites (CMCs) and high entropy alloys. Additional discussion is related to the quality control of the PB-AM materials, and to the prospects of new approaches in material development for PB-AM aiming at aerospace applications.

“…As such, the materials are used today in aerospace applications, such as braking systems, structural components, nozzles, and thermal barriers. Glass-ceramic matrix composites reinforced with continuous SiC fibers have received particular scientific attention as they offer additional attractive properties, such as high strength and stiffness, low density, and chemical inertness at conventional and oxidative environments and over a wide range of temperatures [2].…”

The initiation and propagation of damage in SiC fiber-reinforced ceramic matrix composites under static and fatigue loads were assessed by infrared thermography (IRT). The proposed thermographic technique, operating in lock-in mode, enabled early prediction of the residual life of composites, and proved vital in the rapid determination of the materials' fatigue limit requiring testing of a single specimen only. IRT was also utilized for quantification of crack growth in the materials under cyclic loads. The paper highlights the accuracy and versatility of IRT as a state-of-the art damage assessment tool for ceramic composites.
