“…The AM of microstructures, similarly to the macroscale field, allows the fabrication of complicated shapes that are impossible to obtain with other processes. The AM methods also permit to use a large variety of materials and materials combinations [159][160][161][162][163]. Some of the processes described have been developed by starting from the macroscale to increase their performances and resolutions, making them suitable for building microstructures and MEMS.…”

Recently, additive manufacturing (AM) processes applied to the micrometer range are subjected to intense development motivated by the influence of the consolidated methods for the macroscale and by the attraction for digital design and freeform fabrication. The integration of AM with the other steps of conventional micro-electro-mechanical systems (MEMS) fabrication processes is still in progress and, furthermore, the development of dedicated design methods for this field is under development. The large variety of AM processes and materials is leading to an abundance of documentation about process attempts, setup details, and case studies. However, the fast and multi-technological development of AM methods for microstructures will require organized analysis of the specific and comparative advantages, constraints, and limitations of the processes. The goal of this paper is to provide an up-to-date overall view on the AM processes at the microscale and also to organize and disambiguate the related performances, capabilities, and resolutions.

Colloidal Processing of Complex-Shaped ZrB2-Based Ultra-High-Temperature Ceramics: Progress and Prospects

2022

View full text Add to dashboard Cite

Ultra-high-temperature ceramics (UHTCs), such as ZrB2-based ceramics, are the most promising candidates for ultra-high-temperature applications. Due to their strong covalent bonding and low self-diffusion, ZrB2-based UHTCs are always hot-pressed at temperatures above 1800 °C. However, the hot-pressing technique typically produces disks or cylindrical objects limiting to relatively simple geometrical and moderate sizes. Fabrication of complex-shaped ZrB2-based UHTC components requires colloidal techniques. This study reviews the suspension dispersion and colloidal processing of ZrB2-based UHTCs. The most important issues during the colloidal processing of ZrB2-based UHTCs are summarized, and an evaluation of colloidal processing methods of the ZrB2-based UHTCs is provided. Gel-casting, a net or near-net colloidal processing technique, is believed to exhibit a great potential for the large-scale industrialization of ZrB2-based UHTCs. In addition, additive manufacturing, also known as 3D printing, which has been drawing great attention recently, has a great potential in the manufacturing of ZrB2-based UHTC components in the future.

“…Silicon carbide (SiC) has been considered a primary material for aerospace and nuclear structural applications, such as heat exchangers, fuel cladding tube, and space shuttles, due to its excellent high-temperature mechanical properties, distinguished thermal conductivity, as well as remarkably high oxidation and irradiation resistances. [1][2][3][4][5] However, it is difficult to fabricate fully dense SiC ceramics without sintering additive, due to the high degree of covalently bonded Si-C (∼88%) and a low self-diffusion coefficient of SiC. 6 For example, an extremely high sintering temperature 2500 • C was used by Nadeau to obtain a fully dense SiC ceramics without any sintering additives.…”

A novel Pr 3 Si 2 C 2 additive was uniformly coated on SiC particles using a moltensalt method to fabricate a high-density SiC ceramics via liquid-phase spark plasma sintering at a relatively low temperature (1400 • C). According to the calculated Pr-Si-C-phase diagram, the liquid phase was formed at ∼1217 • C, which effectively improved the sintering rate of SiC by the solution-reprecipitation process. When the sintering temperature increased from 1400 to 1600 • C, the thermal conductivity of SiC increased from 84 to 126 W/(m K), as a consequence of the grain growth. However, an increasing amount of the sintering additive increased the interfacial thermal resistance, resulting in a decrease of thermal conductivity of the materials. The highest thermal conductivity of 141 W/(m K) was obtained for the material having the largest SiC grains and an optimized amount of the additive at the grain boundaries and triple junctions. The proposed Pr 3 Si 2 C 2assisted liquid-phase sintering of SiC can be potentially used for the fabrication of SiC-based ceramic composites, where a low sintering temperature would inhibit the grain growth of SiC fibers.
