FIELD: metallurgy.
SUBSTANCE: present invention relates to a process for UV crosslinking of paint layers. Furthermore, the invention relates to an irradiation apparatus for carrying out the method. Surface of a component is at least partially covered with a coating which comprises a PVD coating arranged between a first paint layer and a second paint layer, and the first paint layer forms a base coat layer on the surface, and the second paint layer forms a top coat layer having a top coat thickness on the PVD coating, wherein at least the top coat layer was produced with UV-curable paint, and, proceeding from the interface of the PVD coating in a region smaller than the top coat thickness, the top coat layer has a lower degree of crosslinking induced by UV light than in the part of the top coat layer connected to said region.
EFFECT: invention provides a paint having good resistance to micro-scratching without being brittle.
