Abstract
A method of manufacturing aluminum foams by super gravity and its effects on the products were investigated. Three-dimensional (3-D) open-cell aluminum foams with pore sizes of 4.5, 3.5, 2.0, and 0.5mm were successfully prepared by infiltration casting with gravity coefficients (G) of 300–900. Increasing the gravity coefficient could effectively overcome the surface tension of molten aluminum infiltrating into the channels of precursor, thus significantly enhancing the product performances of aluminum foams.
