| Abstract Scope |
Open-cell aluminum foams with varying porosities were prepared by combining the method of compressing NaCl into blocks to serve as templates and supergravity infiltration. The prepared open-cell aluminum foams had a pore size of 400 µm and a porosity ranging from 75% to 90%. Experimental results demonstrated that as the compression pressure during block formation increased, the porosity of the foam aluminum increased, and the struts became finer. Increasing the gravity coefficient (G) enhanced the structural integrity of the foam aluminum, leading to the formation of numerous protrusions on the pore wall surface. Due to the ability of supergravity to effectively overcome the infiltration resistance between the preformed NaCl template and the aluminum melt, supergravity infiltration method holds promising potential as a practical new technique for fabricating high-porosity open-cell aluminum foams. |
