Hadi M. A. Abood ^[2] | Noor L. Dawood

Abstract: Electrodeposition of aluminium on copper substrate from aluminium chloride / urea ionic liquid (AlCl3Urea) as electrolyte was conducted at variable conditions. Protected by layer of decan on the top of the liquid under statistic air. The deposit microstructure was monitered by changing temperature, mole ratio, potential and deposition time. The surface morphology of deposited aluminium was investigated by visual microscop Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Energy Dispersive X-ray analysis (EDAX). The effect of changing parameters on the morphology and microstructure of deposit was systematically studied. Results showed that the appearance and the deposit microstructure changed as a function of temperature mole ratio, time and potential. Current density also found to increase with previous parameters except time
