Lotus-type porous Cu-Fe and Cu-Cr with long cylindrical pores was fabricated by centrifugal casting under hydrogen atmosphere and the effect of alloying elements on pore characteristics of lotus-type porous Cu was investigated. For the lotus type porous Cu-Fe alloy, the porosity slightly decreased and the average pore diameter slightly increased with increasing Fe content. For the lotus-type porous Cu-Cr alloy, the porosity sharply decreased and the average pore diameter drastically increased with an increase in the Cr content. From these results, it was found that the pore evolution and growth are affected by alloying element and this leads to the change in the pore characteristics of lotus-type porous Cu-Fe and Cu-Cr alloys.
通过在氢气气氛下离心铸造制备了具有长圆柱形孔隙的莲花型多孔铜铁和铜铬材料，并研究了合金元素对莲花型多孔铜孔隙特征的影响。对于莲花型多孔铜铁合金，随着铁含量的增加，孔隙率略有下降，平均孔径略有增加。对于莲花型多孔铜铬合金，随着铬含量的增加，孔隙率急剧下降，平均孔径大幅增加。从这些结果可以发现，孔隙的演变和生长受合金元素的影响，这导致了莲花型多孔铜铁和铜铬合金孔隙特征的变化。
