Aluminum Bronze (commonly designated as C95400, C95500, or UNS C95800) is a copper-based alloy primarily alloyed with aluminum, typically in the range of 5-12%. It is known for its high strength, excellent corrosion and wear resistance, and good performance in high-stress environments. Aluminum bronze is widely used in applications that demand both mechanical durability and resistance to corrosive environments, such as marine hardware, pump components, and heavy-duty bearings. |

This study suggests the LCD method for manufacturing defect-free continuous CGMs in a single DED process using InssTek’s multi-powder feeding technology without prior powder mixing. |

Experiment SS316L and IN718 powders were simultaneously sprayed from the powder nozzle while the volume fraction of IN718 was linearly increased during 54 layers from 0% to 100%. After that, XRD analysis, OM images, FE-SEM equipped with EDS, BSE detectors and EBSD analysis was conducted for microstructure characterization. |

Schematic of the DED process for CGM fabrication |
|
Conclusions A new method for manufacturing defect-free CGM was proposed in consideration of the composition. It can be adopted various material combinations wherein cracks are induced by the secondary phases during solidification. Also, this method can save time and material, because it does not require pre-powder mixing and can manufacture defect-free parts with FGM by tailoring compositions of local regions only. |
