Abstract (en)
[origin: WO2010106072A2] The invention relates to a method for the electrochemical deposition of aluminum, whereby mat or glossy dense aluminum layers can be obtained. The method comprises the following steps: (a) making an electrolytic device available, said device comprising at least one anode and at least one cathode in an electrolytic chamber, (b) electrochemically depositing the aluminum on the at least one cathode of the electrolytic device from an ionic liquid which contains anions and cations, as well as one or more metal salt(s), and one or more additive(s), a current density of at least 50 A/m2 being applied to the at least one cathode.
