摘要

用制备泡沫铝常用的NaCl作为填料

在脱溶过程中

由于氯离子对Mg基体的严重腐蚀导致Mg基体骨架完全溃散

最终得不到泡沫镁 ;采用MgSO4作为填料

Mg被腐蚀的程度显著降低

制备出了孔隙率为 71.4%、孔径在 1～ 1.4mm之间的泡沫镁。另外

试验发现MgSO4也是制备泡沫铝的理想填料。

Abstract

Foamed Mg alloy cat’t be obtained because Cl - seriously erods and destroys the framework of Mg alloy matrix during the solution of conventional NaCl stuffing materials while the foamed Mg alloy with 71.4% porosity and 1～1.4 mm porous diameters was prepared successfully with MgSO 4 stuffing due to significantly decrease the erosion in Mg.Morever

the experiment reveals that the MgSO 4 is a ideal stuffing for preparation of foamed Al alloy.
