摘要：
Dissolution behavior of Al-Fe-Si alloys with various Fe/Si ratio have been investigated in a 5% NaOH solution. Weight loss of the alloys decreases with decreasing Fe/Si ratio in the alloys. Dissolution process under the NaOH etching treatment is controlled by the cathodic reaction of water reduction. It is electrochemically found that the intermetallic compounds with lower Fe/Si ratio in the Al-Fe-Si alloys cathodically plays poor role in the etching process.
