摘　　要：研究了挂浆法制备泡沫镍的浆料配置工艺,通过粘度测定和浆料沉降实验评价了粘结剂和分散剂含量以及固含量对浆料流变行为和稳定性的影响。结果表明,当浆料中的粘结剂与分散剂含量分别控制在3%~4%与0.2%~0.4%时,固含量达到30%~40%;采用挂浆法浸渍泡沫所得泡沫镍前驱体的孔筋粗细均匀,且其三维通孔性良好。The slurry preparation technology of slurry casting for making nickel foams was investigated. The effects of binder, rheological reagent concentration and solid content on the rheological behavior and stability of slurry can be evaluated by measuring slurry viscosity and sedimentation. The results show that the nickel foams can be obtained when the range of binder, rheological reagent concentration and solid content in slurry is 3%-4%, 0.2%-0.4% and 30%-40% by mass,respectively. The nickel foams with favorable 3-D open cells network structure and uniform muscles can be obtained.
