  • the surface layer is a so-called nano-layer.
  • nanosheets are known per se from the prior art and therefore need not be described in detail.
  • nanosheets are usually made of nanoparticles with a size of less than 100 nm, which settle in the surface roughness and thereby seal the surface, resulting in a significantly reduced surface roughness.

  • the corrosion resistance of the surface layer can optionally consist of a material with a high, medium or small corrosion resistance.
  • Corrosion resistance is particularly important when the paint shop equipment (e.g., bell cup) is made of non-ferrous metal (copper and its alloys) because non-ferrous metals also corrode in combination with demineralized water (DI water). This is important because demineralised water is contained in water-based paints and water-based detergents, so that non-ferrous metal dish plates must be coated with a corrosion-resistant surface layer.
  • DI water demineralized water

  • the surface layer covers the surface of the base body only on partial areas which require an optimization of the cleaning properties.
  • these may be the areas of the lateral surface and the overflow surface that are directly adjacent to the spray-off edge.
  • the inventive principle of optimizing the tendency to fouling or cleanability is not only suitable for bell plates of rotary atomizers, but is also suitable for other paint-carrying components, such as valve housing or valve needles.
  • the invention is also useful for ameliorating other paint shop components that come in contact with a coating agent during operation, such as atomizers (e.g., rotary atomizers), robotic hand axes, robotic arms, or flanges.
  • the invention is useful for improving the cleanability or soiling of components of a paint robot or handling robot (e.g., door opener, hood opener).
  • the invention is also suitable for reducing the tendency to fouling or for improving the cleanability of components of a paint booth, such as covers, gratings, conveyors, windows, wall panels or exhaust ducts.
