Abstract

The disclosure relates to a painting system component, in particular a rotating bell ( 1 ) for a rotating atomizer, including a main body ( 1 ) and a surface coat ( 8 ) at least on a part of the surface of the main body ( 1 ). The surface coat ( 8 ) reduces the tendency of the painting system component to become dirty and/or improves the ease of cleaning of the painting system component.

First claim

The invention claimed is:

1. A painting installation component for directing application of a coating agent, comprising: an annular cup body including one of aluminum, titanium and aluminum oxide materials, the cup body having an at least partially radially inward-facing overflow surface and an at least partially radially outward-facing lateral surface, the cup body having a spraying edge between the overflow surface and the lateral surface, the cup body being configured to receive the coating agent flowing towards the spraying edge within a region bounded by the overflow surface and to direct the coating agent away from the cup body outside of the spraying edge; and a first body coating layer having a base material of niobium and extending on the outwardly facing lateral surface at least part of the cup body, the first body coating layer and the cup body interfacing at a first ion implantation bond, and the inward-facing overflow surface not having a niobium material, and the coating material being made only from niobium, wherein the first body coating layer is configured to provide a coating adherence between a residue of the coating agent and the first body coating layer, the coating adherence being less than a body adherence between the residue of the coating agent and the cup body.

2. The painting installation component of claim 1 , wherein the first body coating layer includes a material with a ductility with an elongation at break of more than 5%.

3. The painting installation component of claim 1 , wherein the first body coating layer includes a material with a ductility with an elongation at break between 0.5% and 5%.

4. The painting installation component of claim 1 , wherein the first body coating layer includes a material with a ductility with an elongation at break of less than 0.5%.

5. The painting installation component of claim 1 , wherein the first body coating layer includes a material with an Rz roughness coefficient larger than 50 μm.

6. The painting installation component of claim 1 , wherein the first body coating layer includes a material with an Rz roughness coefficient between 10 μm and 50 μm.

7. The painting installation component of claim 1 , wherein the first body coating layer includes a material with an Rz roughness coefficient of less than 10 μm.

8. The painting installation component of claim 1 , wherein the first body coating layer is a nanolayer.

9. The painting installation component of claim 8 , wherein the nanolayer includes nanoparticles with a size of less than 100 nm.

10. The painting installation component of claim 1 , wherein the first body coating layer is hydrophilic with a contact angle less than 90°.

11. The painting installation component of claim 1 , wherein the first body coating layer is superhydrophilic with a contact angle less than 5°.

12. The painting installation component of claim 1 , wherein the first body coating layer is hydrophobic with a contact angle greater than 90°.

13. The painting installation component of claim 1 , wherein the first body coating layer is superhydrophobic with a contact angle greater than 180°.

14. The painting installation component of claim 1 , wherein the first body coating layer has a ductility with an elongation at break between 0.5% and 5%, and wherein the first body coating layer has an Rz roughness coefficient of less than 10 μm.

15. The painting installation component of claim 14 , wherein the first body coating layer includes one of a metal oxide, a metal nitride, and a metal-organic compound, and wherein the first body coating layer is a nanolayer including nanoparticles with a size of less than 100 nm.

16. The painting installation component of claim 1 , wherein the first body coating layer extends onto the lateral surface of the cup body.

17. The painting installation component of claim 16 , wherein the first body coating layer is bounded by the lateral surface of the cup body.

18. The painting installation component of claim 16 , further comprising a second body coating layer having a base material of niobium and extending on at least part of the overflow surface of the cup body, the second body coating layer and the cup body interfacing at a second ion implantation bond.

19. The painting installation component of claim 18 , wherein the first and second body coating layers at least partially overlap.

20. The painting installation component of claim 19 , wherein the first and second body coating layers vary in at least one of ductility, roughness, and material composition.
