Abstract
The formation of a porous Cu structure from cast Al–Cu–Co decagonal quasicrystalline alloys has been studied using a selective corrosion technique. Two alkaline solutions were selected based on the electrochemical properties of the constituent elements. Selective corrosion of Al and Co was achieved by chemical immersion of the cast Al–Cu–Co alloy in both 5M NaOH and 0.5M Na2CO3 solutions; values for BET surface-to-weight ratio of up to 30 ㎡/g could be reached. Microstructural analyses indicated that the architecture of the resulting porous structures was composed of a needle-type phase, remaining from the decagonal phase, in addition to Cu and Cu–Co phases.
