This work can contribute the understanding of fabricating composite powders and new ceramic materials.
Due to their low laser absorptivity for sufficient fusion, and high thermal stresses induced by the rapid heating and cooling of laser powder bed fusion (L-PBF) process, the fabrication of dense ceramic components is hindered. In this study, carbon material was mixed with ceramic powders for enhancing the laser absorptivity by leveraging the high absorptivity of carbon. Under the ultra-high-temperature environment of L-PBF, the formation of nanoscale metallic phases was also induced, resulting in the fabrication of multifunctional ceramic materials possessing high strength, high toughness, and high electrical conductivity.
