Ionic liquids magnesium alloy

The electrodeposition of reactive elements like Al, Si, Ge, Ta and a few others is possible. As discussed in Chapter 4.4 the successful electrodeposition of Ti, Mg, Mo and many others in relevant layer thicknesses has not yet been described, though attempts have been made in some cases. Apart from the availability of suitable precursors there is at least one other issue to consider ionic liquids can be reactive. It was found that magnesium and its alloys can form passivating films in ionic liquids with the bis(trifluoromethylsulfonyl)amide (Tf2N) anion, especially in the presence of water. It was found by two of our groups (Endres, MacFarlane) that, under certain circumstances, the Tf2N ion is subject to cathodic... [Pg.371]

The anodic dissolution of magnesium. Mg, has been reported as possible in the basic or buffered ionic liquids that consist of EMI+ and DMPI [20]. However, the deposition of Mg is impossible due to the instability of metallic Mg against these organic cations, whereas the formation of Al-Mg alloys containing Mg up to 2.2 at% has been observed in the acidic EMICI-AICI3 ionic liquid [21]. Calcium and strontium dichlorides, CaCla and SrCla, are soluble in an acidic EMICI-AICI3 ionic liquid and the co-deposition of calcium and strontium with bismuth and copper has been examined in the acidic ionic liquid [22].

Abstract To improve the corrosion resistance of magnesium (Mg) alloys, surface modification is applied in an attempt to produce a corrosion resistant barrier. In this chapter, a new method to deposit aluminum (Al) film on an Mg alloy surface is demonstrated. Electrodeposition of Al on AZ91D Mg alloy, using an acidic aluminum chloride-l-ethyl-3-methylimidazolium chloride ionic liquid (AICI3-EMIC), has been shown to be feasible. The existence of Al coating can cause a substantial increase in corrosion resistance, reducing the susceptibility of Mg alloy to aqueous corrosion. [Pg.519]
