摘要

研究了浸入法制备泡沫铝的发泡新工艺以及工艺参数对发泡效果的影响

得出以工业纯铝粉和TiH2粉为原料

制备气泡均匀、孔隙可控的泡沫铝的工艺参数为:浸入温度为680

60℃

浸入时间为10

保温发泡时间为10

0s。研究结果表明

粉末冶金法浸入式发泡制备泡沫铝的效果好、结构均匀、TiH2利用率高

是一种有较好开发前景的新制备方法。

Abstract

A new foaming method for preparation of foamed aluminum alloy by immersible foaming and effects its variables on foaming were investigated.The foamed aluminum alloy with uniform bubbles and controllable gas-hole can be manufactured with pure commercial aluminum and TiH

powder at immersible temperature of 680～760 ℃ for immersible time of 10～30 s and holding time of 10～60 s.The results showed that powder metallurgy with immersible foaming is a perspective method for preparation of foamed aluminum alloy

possessing the features of high efficiency

even structure and hihg TiH
