The effects of electropolishing on the sub-micrometre structure pattern on the surface of polycrystalline aluminium were investigated. Under constant current, the electropolishing process results in large-area uniform sub-micrometre dot arrays despite the polycrystalline aluminium surface. Effects of temperature on the pattern of the surface structures were also investigated. Experimental temperature was shown to have a great influence on the structure pattern. When the electropolishing temperature increases, the structure of aluminium surface tends to transform from a dot pattern to stripe one and then to a corrosion structure.
