用负压渗流法制备通孔泡沫金属

Preparation of Open Pore Metallic Foam by Negative Pressure Infiltration Process

用负压渗流法和自行研制的填料粒子制备了泡沫金属，通过正交实验研究了影响液态金属渗流的工艺参数。

The open pore metallic foams were prepared by negative pressure infiltration using filling particles prepared by authors. The process parameters which influence the liquid metal infiltration were studied using orthogonal experiment, and the mechanics of which were investigated by the combination of heat transfer and hydrodynamics.
