A study was performed of electrodeposited zinc coatings on aluminium.
The thickness and surface roughness of zinc coatings were found to inc
rease with increasing electrodeposition time. The structural analysis
of zinc coatings showed the presence of zinc and other phases, between
zinc and elements from the electrodeposition solution. The corrosion
of zinc-coated aluminium was observed to be lower than that of bare al
uminium.
