Zirconium carbide/silicon carbide composite material part and additive manufacturing method thereof
The invention discloses a zirconium carbide/silicon carbide composite material part and an additive manufacturing method thereof, and belongs to the technical field of SiC ceramic matrix composite material preparation. The method comprises the following steps: preparing mixed powder, adding a resin material as a binder into the mixed powder to prepare a raw material, and then preparing composite powder; designing a three-dimensional CAD model of the target three-dimensional zirconium carbide/silicon carbide composite material part, and forming the composite powder by adopting an additive manufacturing technology to obtain a green body; carrying out heating treatment on the green body to carbonize the resin material to obtain a prefabricated body; and adding silicon into the preform for reactive sintering to obtain the zirconium carbide/silicon carbide composite material part. The composite powder suitable for additive manufacturing and reactive sintering and the ternary reactive sintering technology of zirconium disilicide, carbon and silicon are researched and developed, the difficult problem of forming of zirconium carbide/silicon carbide composite material complex parts is solved, the sintering process requirement is lowered, deformation and cracking are prevented, and the blank of additive manufacturing in the field is filled.
