| 摘要 |
The present invention relates to a manufacturing method of an RBSiC member having a large size and a complex form with characteristics of ceramics. The manufacturing method of the present invention, as a selective laser sintering process, comprises the steps of: providing a binder and raw materials including silicon carbide particles; forming a thin layer of the raw materials; emitting radioactive rays to parts of the thin layer to be sintered and forming a sintered thin layer; obtaining a non-sintered body by repeating the step of forming a sintered thin layer; impregnating the non-sintered body with a carbon source and obtaining a cured body by curing the non-sintered body impregnated with the carbon source; obtaining a sintered body by carbonizing an organic compound in the cured body; and providing an RBSiC member by injecting silicon to the sintered body and performing reaction sintering treatment of the sintered body. The sintered body comprises 8 to 30 wt% of carbon. |
