几种SiC颗粒增韧防热陶瓷的增韧机制分析 王超1,王宝来1,栾旭1,梁军1 (1.哈尔滨工业大学,黑龙江,哈尔滨,150001) 摘要:通过对热压成形的ZrB_2+SiC,HfB_2+SiC体系以及原位合成的ZrB_2+SiC体系的压痕试验,分析了SiC颗粒增韧防热陶瓷的增韧机制.从力学角度阐述了各体系的增韧机制,从裂纹的扩展方式及耗能角度比较了各体系增韧模式的异同.分析指出,裂纹偏转,裂纹桥联,裂纹分叉钉扎等多种机制的协同作用是SiC颗粒增韧防热陶瓷韧性大幅提高的主要原因.基体与增强相之间的化学匹配关系也是影响增韧效果的原因之一. 关键词:防热陶瓷; 增韧机制; SiC颗粒; 压痕试验; thermal protective ceramics; toughening mechanisms; SiC particle; indentation test; [全文内容正在添加中] ......
