To form glossy plating of Al on a Cu substrate, electroplating of Al was conducted in an ionic liquid mixture of 1-ethyl-3-methylimidazolium chloride and aluminum chloride (EMIC-AlCl3) containing 1,10-phenanthroline (Phen). The electroplated surface smoothness obtained using an Al-plate counter electrode was improved by stirring of the electrolyte. The reflectivity at the center of the specimen surface formed by a stirring rate of 400 rpm was the highest at 74.7% with stirring rates from 0 to 400 rpm and the reflectivity of the specimen was higher at the edge than at the center. The results suggest that the glossy surface of the substrate was enhanced by uniformity of the electrolyte in contact with the substrate. When the counter electrode was replaced with the Al mesh, the electroplated surface was glossy throughout the surface without stirring. Diffusion of the electrolyte through the Al mesh might have produced an effect similar to stirring of the electrolyte.
