利用放电等离子烧结系统提供的脉冲电流辅助热等静压技术制备了金属闭孔材料。采用该技术烧结了包覆有Ni-P合金的酚醛树脂球形颗粒。获得了不同尺寸的蜂窝状镍合金试样。压缩试验表明，具有较小孔尺寸的材料的压缩强度高于具有较大孔尺寸的材料。在粗孔结构中加入细孔可以提高试样的抗压强度。
A hot isostatic pressing technique assisted by the pulse current supplied by a spark plasma sintering system was used to fabricate metallic closed cellular materials. Phenol resin spherical particles coated with a Ni–P alloy were sintered using this technique. Cellular nickel alloy samples with different cell sizes were obtained. Compressive tests showed that the compressive strength of this material with a smaller cell size was higher than that with a larger cell size. The addition of fine cells to a coarse cellular structure can improve the compressive strength of the specimen.
