| Abstract Scope |
Traditional additive manufacturing methods for processing of SiC-Si composites typically involve binder jetting of SiC, followed by liquid silicon infiltration. This multi-step process is both time- and energy-intensive, often leading to prolonged lead times and increased manufacturing costs. Here, we propose a more efficient approach: direct additive manufacturing of SiC-Si composites using Directed Energy Deposition (DED) with blended SiC and pure Si powders. The proposed method is versatile and significantly streamlines the production process, reducing lead time and enhancing material density. The DED’ed composite samples were characterized by optical and scanning electron microscopy, X-ray diffraction, hardness and nanoindentation tests. Experimental findings confirm that the DED process yields in-situ manufacturing of high-quality SiC-Si composites, offering substantial improvements in manufacturing efficiency and material performance. |
