Scaling-up of the aluminium process from ionic liquids

3th-8th July 2016 was hold in Vienna (Austria) the 26th EUCHEM Conference on Molten Salts and Ionic Liquids. This well established biannual conference devoted to intense knowledge exchange in the field of molten salt and ionic liquids. The conference covers both fundamental aspects as well as all kind of applications in ionic media and nearly 300 scientific contributes (oral and posters) were presented. Among the over 200 participants, Stefano Caporali and Stefano Martinuzzi from INSTM (Italy) take part to the event and presented results from the Scail-UP project. Two different posters were presented: the first contribution was dealing on the effect of three common transition metal ions, i.e. Ni2+, Cu2+ and Fe2+ that accidentally can be present in the Al-electroplating bath as consequence of contamination. The effect of increasing concentrations of these metal ions in the electroplating bath was evaluated by means of cyclic voltammetry, SEM and rugosimetry providing a direct insight about the effect of such foreign atoms on the grown and composition of metallic Al layers electrodeposited from chloroaluminate Ils. The second one was aiming to the production of aluminium matrix MMC (metal matrix composite) coatings obtained via co-deposition, at room temperature, of metallic aluminium and ceramic microparticles dispersed in a chloroaluminate IL. The morphology and microstructures of the coatings were evaluated by means of SEM-EDS on the deposit surface and the cross-section. The results were related to the electroplating bath composition (nature and amount of dispersed particles) and the electrodeposition parameters (current density and deposition potential) in the attempt to determine the optimal conditions for the deposition of aluminium-based MMC coatings.
