Additive manufacturing method of silicon carbide ceramic matrix composite material structure/functional part
The invention discloses an additive manufacturing method of a silicon carbide ceramic matrix composite material structure/functional part, which comprises the following steps: weighing silicon carbide, carbon fibers and silica powder, carrying out vacuum drying, carrying out chemical vapor deposition treatment on the carbon fibers to form amorphous carbon on the surface of the carbon fibers, carrying out chemical vapor deposition treatment on the silicon carbide to form a silicon film on the surface of the silicon carbide, uniformly mixing the silica powder, the carbon fibers and the silicon carbide to obtain mixed powder, setting forming parameters and a scanning strategy, outputting the structure/functional part model in an STL format, importing the structure/functional part model into selective laser melting forming equipment, introducing the mixed powder into the selective laser melting forming equipment, and carrying out structure/functional part forming in the atmosphere of shielding gas, so that additive manufacturing of the silicon carbide-based ceramic structure/functional part is achieved. The method is safe and efficient, the manufactured structure/functional part is high in density and uniform in structure, near-net-size forming can be achieved, and aftertreatment is not needed.
