Abstract

Lewis acidic 1-allyl-3-methylimidazolium chloroaluminate ionic liquids were used as promising electrolytes in the low-temperature electrodeposition of aluminium.Systematic studies on deposition process have been performed by cyclic voltammetry and chronoamperometry.The surface morphology and X-ray diffraction(XRD) patterns of deposits prepared at different experimental conditions were also investigated.It was shown that the nu-cleation density and growth rate of crystallites had a great effect on the structure of aluminium deposited.The crys-tallographic orientation of deposits was mainly influenced by temperature and current density.Smooth

dense and well adherent aluminium coatings were obtained on copper substrates at 10-25 mA·cm

-2

and 313.2-353.2 K.More-over

the current efficiency of deposition and purity of aluminium have been significantly improved

demonstrating that the ionic liquids tested have a prospectful potential in electroplating and electrorefining of aluminium.
