具有高耐腐蚀性的多孔金属体及其制造方法
摘要：
一种多孔金属体，其具有由至少含有Ni和Cr的合金构成的三维网状结构，所述多孔金属体具有由中空芯部和外壳形成的骨架，其中，当将所述外壳的横截面在厚度方向上均匀分为三个部分，即外侧部分、中央部分和内侧部分时，并且当将所述外侧部分、所述中央部分和所述内侧部分中Cr的重量百分数浓度定义为符号a、b和c时，a、b和c满足由表达式(1)表示的关系：|(a+c)/2-b|/(a+b+c)/3
摘要（英）：

A porous metallic body has a three-dimensional network structure composed of an alloy containing at least Ni and Cr, the porous metallic body having a skeleton formed of a hollow core and a shell, in which when a cross section of the shell is evenly divided in the thickness direction into three portions, i.e., an outer portion, a central portion, and an inner portion, and when concentrations in percent by weight of Cr in the outer portion, the central portion, and the inner portions are defined as a, b, and c, a, b, and c satisfy the relation given by expression (1):
