| 摘 要： | 利用透射电镜和高分辩电子显微术研究了ＺｒＯ_２－Ｎｉ功能梯度材料（ＦＧＭ）的界面形态与精细结构。结果表明，组元Ｎｉ和ＺｒＯ_２，以直接结合为主，无明显界面反应。ＺｒＯ_２中ｔ／ｍ相界完全共格，存在大量界面结构台阶。此外，在Ｎｉ孪晶界附近存在较多生长缺陷──Ｆｒａｎｋ位错。

| Abstract: | The morphology and fine structure of phase interface in ZrO2-Ni functionally gradient material (FGM) were investigated by TEM and HREM. Most of the interfaces between ZrO2 and Ni components in the FGM are directly connected and no interface reaction has been detected. The t / m interface in ZrO2 component is coherent and contains structural steps. Furthermore, there are quite many growth defects-Frank dislocations near the Ni twin boundary. |
