英刊报道,用松散的粉末制造多孔隙材料的高压放电成形工艺。它利用电容器组突然放电时的电能,通过被包容在绝缘容器里的导电粉末柱(见图1),形成电流脉冲而产生高温和径向磁性压缩力,压实和焊合粉末柱,使之成为既连续且长径比大、密度小、可塑和具有机械强度的多孔物体。

British Journal reported that the use of loose powder porous material manufacturing high-pressure discharge forming process. It takes advantage of the electrical energy of a capacitor bank when it is suddenly discharged to create a current pulse that creates a high temperature and radial magnetic compressive force through a conductive powder column (see Figure 1) contained in an insulated container, compacting and welding the powder column to Become both continuous and large aspect ratio, density, plasticity and mechanical strength of porous objects.
