Study on electrodeposition of Al on W-Cu substrate in AlCl3Â +Â LiAlH4 solutions

► Electrodeposition of Al coating on W90Cu10 foils. ► AlCl3 + LiAlH4 Non-aqueous solution was used as electrolyte. ► The effects of the molar ratios of AlCl3/LiAlH4, current density and plating time on the crystal orientation of Al coatings were studied.
