| Abstract: | The technique of fabricating the porous alumin um alloy with thevacuum penetration system has been researched and developed.It decreas e d the anti-pressure of the gas inside the mold,which is favorable to the fabric ation of thin hole(diameter 0.4～0.7mm)porous aluminum.The problem that the infi ltration is difficult in fabrication of the thin hole porous aluminum alloy has been solved.The testing results show that the sound absorbent property of the po rous aluminum alloy in high frequency range is good. |
