Abstract (en)
[origin: EP0648863A1] Aluminium-containing substrate for enamel coatings, comprising, at least on the areas intended for enamel coating, a surface layer of aluminium or an aluminium alloy and, on this surface layer, an oxide layer which constitutes an isotropic barrier layer with a thickness of from 0.01 to 1 mu m and a dielectric constant of between 5 and 10. Adjacent to this barrier layer there may also be a porous oxide layer with a thickness of from 0.1 to 10 mu m. An enamel coating having a thickness of, for example, from 50 to 200 mu m is applied to the substrate. The enamelled substrates can be employed as exterior panelling on vehicles or exterior facing on buildings, the enamel-coated substrates being outstandingly protected against external influences.
