Abstract: The invention relates to an electrolyte for the electrodeposition of aluminium from aprotic solvents containing a compound of the formula: N(R1)4X.(m-n-o)Al(C2H5)3.nAlR23oAlR33, wherein R1 is a C1 to C4 alkyl group, X is F, Cl or Br, m is equal to 1 to 3, preferably 1.7 to 2.3, n is equal to 0.0 to 1.5, preferably 0.0 to 0.6, o is equal to 0.0 to 1.5, preferably 0.0 to 0.6, R2, R3 is a C1 or C3 to C6 alkyl group, wherein R2 is unequal to R3, in an organic solvent. A further object of the invention is a method for producing the electrolyte, a method for coating and the coated material parts.

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.

Abstract: The invention relates to a coated workpiece comprising a substrate, a metallic layer applied to said substrate, and a layer containing a aluminum/magnesium alloy applied to the intermediate layer. The invention also relates to a method for producing this coated workpiece.
