  • Patent number: 7468123
    Abstract: The invention concerns a method for electrolytic coating of materials with aluminum, magnesium or aluminum and magnesium alloys. The method is characterized in that the material is pretreated by being immersed in an electrolytic solution, where it is anodized, the electrolytic coating being performed immediately after in the same electrolytic solution.

  • Patent number: 7235681
    Abstract: The invention relates to a method for producing electrolyte solutions consisting of trialkylaluminium AlR3, M1AlR4, M2AlR4 and an aromatic hydrocarbon. According to the invention, a mixture of M1OR and M2OR is reacted with trialkylaluminium AlR3 at temperatures below 25° C. in an aromatic hydrocarbon. M1AlR4/M2AlR4 is isolated from the obtained mixture and a ready-for-use electrolyte for the electrochemical deposition of aluminum-magnesium alloys is obtained by the addition of aromatic hydrocarbon.
