中文摘要：
采用电子束物理气相沉积（EB-PVD）技术制备了金属（NiCoCrAl）／陶瓷（Y203-ZrO2）微叠层材料，并对其微观结构和力学性能进行了分析。结果表明，金属层和陶瓷层间界面较为平直、清晰。金属层由γ-Ni相构成，层中晶粒为较大的等轴晶。陶瓷层由c-ZrO2和t-ZrO2两相组成，层中晶粒为较小的柱状晶。在金属层的顶部，存在一些均匀分布的微孔。这种材料在室温拉伸试验中表现出无宏观塑性变形的脆性断裂特征。断口分析表明，金属层起到了阻碍裂纹扩展的作用，且层界面存在脱粘的现象。
英文摘要：
The microstructure and mechanical properties of metal （NiCoCrAl）/ceramic （Y2O3-ZrO2） microlaminate composites produced by EB-PVD was investigated. The results showed there were flat and distinct interfaces between metal and ceramic layers. Metal layers were found to consist of γ phase and has a relatively large equiaxed grain structure. While ceramic layers included cubic and tetragonal phases, in which a small columnar grain structure was observed. Furthermore, some evenly distributed micropores in the upper part of metal layers were also seen. The microlaminates exhibited brittle-like behavior without macroscopic plastic deformation in room temperature tensile tests. Examination of fracture surfaces from the samples revealed that the metal layers blunted cracks in the ceramic layers and that delamination at interfaces between layers occurred.
