Abstract:
1. A method of fabricating an aluminum porous body, comprising the steps of: mixing an aluminum brazing flux with a raw material powder, the brazing flux comprising at least one of a chloride-based flux including zinc chloride and a fluoride-based flux including aluminum fluoride, and the raw material powder comprising at least one of pure aluminum and aluminum alloy; controlling the relative density of the aluminum porous body within a range of from 5 to 80% with respect to the theoretical density of pure aluminum by mixing a spacer material with the aluminum brazing flux and raw material powder; and shaping the raw material powder via the flux by irradiating the raw material powder mixed with the flux with a laser; and sintering the raw material powder by irradiating the shaped raw material powder with electromagnetic waves; and removing the flux and the spacer material by washing after sintering.
