Claims18
An ionic liquid aluminum electroplating solution comprising:
- an ionic liquid;
- an aluminum salt;
- and
- an effective amount of propylene carbonate.
A method for producing an aluminum coating on a substrate, the method comprising:
- applying aluminum or an aluminum alloy to at least one surface of the substrate by electroplating under electroplating conditions in an ionic liquid aluminum electroplating solution comprising an ionic liquid, an aluminum salt, and an effective amount of propylene carbonate.
A process for electroplating aluminum or an aluminum alloy from an ionic liquid aluminum electroplating solution comprising:
- adding an effective amount of propylene carbonate to an ionic liquid and aluminum salt solution thereby forming the ionic liquid aluminum electroplating solution;
- and
- electroplating at least one surface of a substrate under electroplating conditions in the ionic liquid aluminum electroplating solution to form an aluminum coating on the substrate.
