Abstract (en)
[origin: EP1403402A1] In the electrolytic coating of substrates with aluminum, magnesium or an Al/Mg alloy the substrate is pretreated by dipping in an electrolyte and anodically connecting it, the coating immediately following in the same electrolyte with the bath containing an organoaluminum compound as the electrolyte; and a halogen-free aprotic solvent for the electrolyte. In the electrolytic coating of substrates with aluminum, magnesium or an Al/Mg alloy the substrate is pretreated by dipping in an electrolyte and anodically connecting it, the coating immediately following in the same electrolyte with the bath containing: (a) an organoaluminum compound of formula (I) or (II); and (b) a halogen-free aprotic solvent for the electrolyte. n = 0 or 1; M = sodium or potassium; and R1 - R4 = 1-4C alkyl.
