摘要

研究了用反应烧结碳化硅制备几何复杂机械工程产品的两种方法——烧结前机械加工聚合件和加压热滑铸造成型方法。所得碳化硅陶瓷材料的密度为3.04 ~ 3.07 g/cm3，孔隙率≤1%，抗弯强度为320 ~ 360 MPa。碳化硼改性碳化硅材料的密度为2.72 g/cm3，孔隙率约为1%，抗弯强度为280 MPa。

Methods of Forming Geometrically Complex Manufactured Products from Silicon-Carbide Based, Heat-Resistant, Ceramic Materials

The possibility of producing geometrically complex mechanical-engineering products based on reaction-sintered silicon carbide using two methods was investigated — mechanical processing of polymerized workpieces before sintering and molding by hot slip casting under pressure. The resulting silicon carbide ceramic materials are characterized by low density of the order of 3.04 – 3.07 g/cm³, porosity ≤ 1%, and bending strength 320 – 360 MPa. Materials based on silicon carbide modified with boron carbide have density 2.72 g/cm³, porosity about 1%, and bending strength of 280 MPa.
