摘要/Abstract

摘要： 为了研究维氏压痕裂纹对常压固相烧结碳化硅陶瓷(SSiC)材料力学性能的影响, 通过扫描电镜观察了0.1~100 N的压痕载荷下产生的表面裂纹及裂纹剖面的状况, 并测试了相应载荷下的力学性质, 探讨了压痕法测量SSiC材料硬度、韧性等力学性质的适当压力载荷. 结果表明, SSiC材料压痕裂纹起始的临界压力载荷介于0.1~0.2 N; 当压痕载荷小于0.5 N时, 裂纹尺寸小于5 μm, SSiC材料的平均弯曲强度受影响程度较小. 此外, 当压痕载荷为10 N以上时, 压痕法测得的维氏硬度值趋近定值, 且所得到的裂纹是半圆形裂纹, 因此, 10 N为采用压痕法准确测量SSiC材料硬度及韧性的最低压痕载荷值.

Abstract: In order to study the effects of Vickers cracks on the mechanical properties of solid-phase-sintered silicon carbide (SSiC for short) ceramics, the indentation cracks and the crack profiles were observed after loading 0.1–100 N loads on the SSiC samples by SEM. The critical indentation load for Vickers crack initiation in SSiC ceramics lies between 0.1 N and 0.2 N. Indentations by loads lower than 0.5 N have limited influence on bending strength. And if the indentation loads is higher than 10 N, the obtained hardness floats around 24.2 GPa and the cracks are half-coin type. The proper Vickers indentation load range for SSiC ceramic hardness and toughness tests are determined to be 10 N or above.

Key words: silicon carbide ceramic, indentation load, mechanical properties
