本专利涉及到通过把金属熔体和无机的轻质材料一起混合并随即凝固熔体来制取含有填料的海绵状金属的方法。在减压或在高压下把金属熔体注到无机的轻质材料充填物中。众所周知,泡沫状的金属物体是用金属氢化物(例如用氢化锆)作为气体分解物质来制取的(美国专利2751289)。这个制取方法成本较高,在制取工艺上较为复杂。此外,在制
This patent relates to a method of preparing a filler-containing spongy metal by mixing together a metal melt and an inorganic light material and then solidifying the melt. The molten metal is injected into the inorganic lightweight material filling under reduced pressure or under high pressure. It is well-known that foamed metal objects are made from metal hydrides, for example with zirconium hydride, as gas-decomposing substances (U.S. Pat. No. 2,751,289). The cost of this preparation method is relatively high, in the preparation process is more complicated. In addition, in the system
