Abstract

The electrodeposition of aluminium on brass (63/37) from a dry AlCl3/NaCl melt (80wt.% purified AlCl3, 20 wt.% NaCl) using static as well as rotating cathodes and a variety of conditions has been studied. The current efficiency of the process is very high and the electrodeposits are smooth, fine grained and silver white in appearance. Although at lower temperatures, there is a tendency for flakes to be formed locally these are easily removed and do not affect the overall quality of the electroplate.
