A deposition device may deposit, on a substrate, a binder layer that includes a first set of magnetic flakes and a second set of magnetic flakes and may cause, when a temperature of the binder layer satisfies a temperature threshold (e.g., a Curie temperature of the first set of magnetic flakes), a magnetic field to be applied to the binder layer to cause the first set of magnetic flakes and the second set of magnetic flakes to be oriented according to the magnetic field. The deposition device may cause, when the temperature of the binder layer ceases to satisfy the temperature threshold, another magnetic field to be applied to the binder layer to cause only the second set of magnetic flakes to be oriented according to the other magnetic field.

The method comprises: providing an ink mixture comprising an ink and an organic carrier, the carrier comprising a polymerisable organic material; arranging the ink mixture and the decorative element in a plasma; and allowing the ink mixture to polymerise on a surface of the decorative element to form a polymerised colour coating. The polymerisable organic material may comprise a polymerisable siloxane or a polymerisable oxysilane.

In a method for coating motor vehicle wheel rims, a polymer priming layer, a polymer intermediate layer, a decorative layer of a heat-cured polymer layer with embedded flake-like metal pigments covering the visible surface of the decorative layer, and a polymer cover layer are consecutively applied to the wheel rim metal surface. The coated wheel rims achieve a polished metal appearance by producing the polymer intermediate layer with a high-gloss surface and applying the decorative layer to the high-gloss surface of the polymer intermediate layer in the wet spraying method with a layer thickness of max. 2 μm, where it is dried at ambient temperature and, before applying the polymer cover layer, it is fixed to the polymer intermediate layer via a thermal post-treatment so that it adheres to the surface thereof with a cross-cut pull-off strength of Gt=0 to Gt=2.
