摘要

为了提高凝胶注模反应烧结碳化硅的综合性能

选用糠醇为前驱体

对高温脱脂后多孔状态的坯体进行前驱体浸渍处理

以期通过提高反应烧结后坯体中的碳化硅含量来提升其性能。研究了浸渍处理对碳化硅密度以及微观结构的影响。结果显示:未经浸渍处理的样品平均密度为2.93 g/cm

折合碳化硅含量(体积分数)为68.2%;经糠醇浸渍处理后的样品平均密度为3.06 g/cm

折合碳化硅含量(体积分数)为83.0%

碳化硅含量增加了21.7%。由糠醇热解碳生成的β-SiC尺寸细小

在光学显微镜下形貌与原来的α-SiC难以区分

但在坯体中的分布并不均匀。对样品进行了性能测试

结果显示:经糠醇浸渍处理后

坯体平均抗弯强度从343.3 MPa提高到382.0 MPa

增幅为11.3%;平均弹性模量从303.5 GPa提高到353.8 GPa

增幅为16.6%。得到的数据表明反应烧结碳化硅各方面性能均有不同程度的提高。

Abstract

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/cm

after reaction sintered

namely the silicon carbide content is 68.2%. The average density increases to 3.06 g/cm

after impregnation

namely the silicon carbide content is 83.0%. The silicon carbide content increases by 21.7%. The scale of β-SiC generated by furfuryl alcohol pyrolytic carbon is fine. Under the light microscope

the appearance of β-SiC is difficult to distinguish from the original α-SiC

but the distribution of β-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.
