摘要:

SiC陶瓷具有高强度和良好的热稳定性, 在航空航天、热端部件等领域有着广泛的应用前景。随着对大尺寸和复杂形状SiC陶瓷需求的日益增长, 3D打印技术在制造周期、成本及可靠性等诸多方面明显优于传统减材、等材制造方法, 越来越受到重视。3D打印方法众多, 各具特点: 立体光刻(Stereolithography, SLA)技术可以实现高精度和优良的表面质量, 但实际操作中往往需要设计支撑结构, 再加上残余应力和低固含量等问题, 极大限制了其发展; 激光选区烧结(Selective laser sintering, SLS)技术具有较强的材料普适性, 适用于高分子、金属和陶瓷等多种材料, 可实现大尺寸快速成形, 且制造成本较低, 但其成形素坯表面质量较低, 需进行后续加工; 熔融沉积(Fused deposition modeling, FDM)技术制备的SiC陶瓷材料可借助反应烧结实现致密化, 但成形素坯存在层间结合强度低、表面有较明显条纹等缺陷, 并且成形速度相对较慢, 不适合构建大型零件, 因此在实际生产中受到限制。本文综述了近五年来3D打印SiC陶瓷的最新研究进展, 讨论了成形素坯的后续高温致密化处理方法及其基本物理性能, 并展望了3D打印SiC陶瓷材料的未来前景。新型3D打印技术及其与多种打印方式的融合将在陶瓷宏微观结构的精细化中发挥重要作用, 或将成为未来的重要发展趋势。

Abstract:

SiC ceramics exhibit high strength and thermal stability, rendering them highly suitable for applications in space and thermal components. However, the growing demand for large-sized and complex-shaped SiC ceramics necessitates advanced manufacturing techniques. In comparison to traditional reduction and equal material manufacturing methods, 3D printing technology offers significant advantages in various aspects, such as manufacturing cycle, effective cost, and reliability. There are many 3D printing methods, each with distinct characteristics. Stereolithography (SLA) is capable of achieving high precision and superior surface quality. However, its practical applications often necessitate special design of support structures. Additionally, issues such as residual stress and low solid content significantly hinder its further development. Selective laser sintering (SLS) exhibits strong material compatibility, which is suitable for a wide range of materials, including polymers, metals and ceramics. This technology enables large-scale rapid prototyping at low manufacturing costs. But its surface quality of the formed billet is typically insufficient, which needs additional post-processing. Fused deposition modeling (FDM) though facilitates the preparation of SiC ceramics via reaction sintering, proves unsuitable for constructing large components which restricts its applicability in actual production contexts, due to its inadequate interlayer bonding strength coupled with pronounced surface striations and slower forming speeds. This paper reviews the latest research progresses of 3D-printed SiC ceramics and analyzes the subsequent high-temperature densification treatments of green bodies, along with their fundamental physical properties. Finally, it proposes some prospects of 3D printing of SiC ceramic materials, and strengthens integration of new 3D printing technologies and various printing methods for fine regulation of ceramics’ macro- and micro-structures.
