中文摘要：

介绍了基于喷射电沉积的逐层扫描法制备块状多孔金属镍的原理，利用该工艺在自行研制的试验装置上制备块状多孔金属镍。利用电子扫描显微镜（SEM）对多孔金属镍块状试样的表面形貌、微观组织结构及孔隙率进行检测，对表面显微硬度和压缩性能进行测试。结果表明：多孔金属镍样品的多孔层由向上生长的枝状晶围成三维连通孔隙，通孔分布均匀致密。经SEM分析铸层表面，可见枝状晶分支由菜花状的晶胞叠加生长形成。使用加工电流密度为900A／din。时，制备的块状样品孔隙率为61．5％。表面的显微硬度HV为330．5。压缩性能的检测结果表明，多孔金属的抗压屈服极限为11．85MPa。应力曲线存在一个很宽的塑性平台，具有典型的塑性多孔材料特征。

英文摘要：

The bulk porous nickel sample was introduced and made by jet scanning electrodeposition forming. The surface morphology, microstructure,grain size of the micro-cell structure of deposition, were studied and analyzed by means of SEM, and the mechanical properties of the sample were also studied,such as surface micro-hardness and compressive property. The results show that, using jet scanning electrodeposition in current density of 900A/dm^2 ,the prepared sample＇s porosity is 61.5%. The surface micro hardness of the sample reaches to HV 330.5. The compressive yield stress of porous nickel is 11.85MPa, which has a large number of plastic deformations of the absorption capacity.
