Abstract

The use of mechanochemical activation of the powder at the stage of mixing the components and consolidation by spark plasma sintering made it possible to synthesize material based on silicon carbide, which has a weight loss of less than 0.04% when tested for heat resistance at 1500°C for 100 h. A ceramic material was produced at a consolidation temperature of 1800°C, its hardness was 32 GPa and a critical stress intensity factor was 6 MPa m^1/2.

硼和碳改性添加剂对碳化硅陶瓷材料耐热性影响的研究

摘要

在混合组分和通过火花等离子体烧结进行固结的阶段使用粉末的机械化学活化，可以合成基于碳化硅的材料，当在1500°C下进行耐热性测试时，该材料的重量损失小于0.04％ C持续100小时。在固结温度为1800℃下制造陶瓷材料，其硬度为32GPa，临界应力强度因子为6MPa m ^1/2。
