摘要
制备了用Ca-PSZ进行相变强韧化FMA的复合陶瓷材料,发现在Ca—PSZ加入量为9%时其宏观力学性能达到峰值;从SEM微观形貌和EDS能谱分析结果出发研究了FMA基体材料的强度形成因素、Ca—PSZ补强的机理;通过XRD衍射分析及相成分的近似定量分析阐明了半稳定化ZrO_2相交增韧作用的材料学本质;从微观角度提出ZrO_2相变增韧和割裂作用综合影响的结果是复合材料的宏观性能存在峰值的原因。
The Ca-PSZ/FMA composite material strengthened by Stress - Induced - Phase - Transformation (SIPT) is produced. Its macro mechanical properties reach at the peak when content of Ca-PSZ is 9% . The strength mechanism and toughening function are studied by XRD phase structure, SEM micro appearance and EDS ingredient. The cause of peak in the mechanical properties is explained by the micro analysis view.
