I am trying to electropolish the surface of a 3003 aluminum sample to analyze in the SEM. I was wondering if anyone knew what electrolyte and electropolishing paramaters work for this alloy. So far I have used phosporic+ethanol+water at 50V for 2 minutes with minimal success.Aluminium needs deoxidizing also called as desmutting after electropolishing. This is done in a hot chromic acid bath for nearly for 5 minutes.Other related question
