摘要 | To improve the mechanical properties of the gel-casting reactive bonded silicon carbide, furfuryl alcohol was selected as the precursor, and the porous state green body after degreasing at high temperature was processed by precursor impregnation. It is expected to improve the performance of the silicon carbide by improving its content in the body after reaction sintered. The density and the microstructure after the impregnation process were investigated. The results show that the average density of the sample without impregnation process is 2.93 g/cm3after reaction sintered, namely the silicon carbide content is 68.2%. The average density increases to 3.06 g/cm3after impregnation, namely the silicon carbide content is 83.0%. The silicon carbide content increases by 21.7%. The scale of -SiC generated by furfuryl alcohol pyrolytic carbon is fine. Under the light microscope, the appearance of -SiC is difficult to distinguish from the original -SiC, but the distribution of -SiC is not uniform in the body. A performance test was conducted with the samples. It shows that the average flexure strength has increased from 343.3 MPa to 382.0 MPa after impregnation, and strength increased by 11.3%. The average elastic modulus has increased from 303.5 GPa to 353.8 GPa after impregnation, the elastic modulus increased by 16.6%. These data indicate that the mechanical properties of the silicon carbide have been improved in varying degrees. 2015, Chinese Academy of Sciences. All right reserved. |
