Electrodeposition of metals and alloys in ionic liquids has been employed in a broader range of fields. Issues regarding the evolution of hydrogen, toxicity of reagents can be overcome by utilizing ionic liquids. This review outlines the current state of electrodeposition of various types of metals and their alloys in ionic liquids with particular focus on the work within the last decade. The metals are categorized into four groups and special attention is paid to the reactive metals that cannot possibly be deposited from traditional aqueous solutions. [ABSTRACT FROM AUTHOR]

Abstract: In this paper, a new method to prepare Al–8.5Fe–1.3V–1.7Si (FVS0812) alloy by spray co-deposition with added its over-sprayed powders was studied. Two kinds of powders which are different in particle size (≤43, 43–74μm) were used in the new process. Under the same experimental conditions, the alloys were produced by spray deposition without powders and the spray co-deposition. The deposited alloys were subsequently hot extruded with an extrusion ratio of 16:1 at 450°C. The results showed that the addition of over-sprayed powders refined the microstructure and improved the mechanical properties, and the effect of the fine over-sprayed powders was more evident than that of the coarse powders. The ultimate tensile strength was enhanced from 360.5MPa (without powders) to 433.3MPa (≤43μm) and 392.4MPa (43–74μm). The mechanical properties increase is mainly due to the over-sprayed powders pulverizing melt effectively, absorbing heat greatly and increasing the number of heterogeneous nuclei in matrix, which result in the enhancement of cooling rate and the refinement of microstructure.
