The electrorefining of aluminum alloy (A360) in ionic liquids at low temperatures has been investigated. The ionic liquid electrolyte was prepared by mixing anhydrous AlCl3 and 1-Butyl-3- methylimidazolium chloride (BMIC) in appropriate proportions. The effect of the cell voltage temperature, and the composition of the electrolyte on the electrorefining process has been studied. The characterization of the deposited aluminum was performed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The influence of experimental parameters such as cell voltage and concentration of AlCl3 in the electrolyte on the deposit morphology was discussed. The composition of the aluminum deposits was analyzed using X-ray fluorescence spectrometer (XRF). Aluminum deposits with purity higher than 99.89 % were obtained. At a cell voltage of 1.0 V vs. Al/Al(III), the energy consumption was about 3 kWh/kg-Al. The main advantage of the process is low energy consumption compared to the existing industrial aluminum refining process.

Hardness of the pseudobinary transition metal aluminum nitride (T-Al-N) films is improved with increasing the AlN content as far as the B1structure is maintained. A drastic change in the compositional dependence of the hardness corresponds to the phase change of the pseudobinary nitride from B1(NaCl) to B4(wurtzite) structure. Predicted value of AlN content for the drastic change agrees with the AlN content determined experimentally. Hardness of various T-Al-N films was closely correlated with the bulk modulus calculated from interatomic distance based on the power functional formula. The improvement of hardness is attributed to the inherent increase of bulk modulus due to dissolution of AlN into transition metal nitride.
