摘要
基于我们以前发表的精细复合Ｎｉ－ＺｒＯ２的热渗流现象；采用薄层迭层法，设计和制备了２８种不同成分分布曲线Ｙ［ｐ，Ｙ（１）］（Ｘ）的Ｎｉ－ＺｒＯ２ＦＦＧＭ；并用电子探针和扫描电子声显微镜分析了其成分分布、应力分布和组织结构；最后得到一种成分分布曲线为Ｙ［１，４０］（Ｘ）的Ｎｉ－ＺｒＯ２ＦＦＧＭ，它具有较显著的应力缓和效果、较高的结构完整性和致密度．本文为Ｎｉ－ＺｒＯ２ＦＦＧＭ的优化设计、制备和研究其成分分布及应力分布提供了一种崭新而有效的方法．
Based on our previous study on the thermal percolation phenomenon existing in the Ni-ZrO2 composite prepared by fine combination technology, the fine Ni-ZrO2 Functionally Gradient Material (FGM) with twenty eight kinds of composition distribution curves was designed and synthesized. The microstructure and composition and stress distributions of the materials were analyzed by electron probe and scanning electron acoustic microscopc. The experimental results show that the fine Ni-ZrO2 functionally gradient materal with the composition distribution curve of Y[1,40](X) possesses the best effect of internal stress relaxation, lower porosity and higher integrality in structure. It seems that to a certain extent this paper may open a new prospect for the optimum design, fabrication and evaluation of the Functionlly Gradient Materials.
