METHOD FOR APPLYING A CORROSION PROTECTION LAYER TO A SURFACE TO BE PROTECTED OF A COMPONENT

Abstract

A method for applying a corrosion protection layer to a surface to be protected of a component: including providing the corrosion protection layer having a first surface and a second surface arranged opposite this, laying the first surface of the corrosion protection layer on a bottom face of a mold, laying the surface to be protected of the component on the second surface of the corrosion protection layer so as to enclose a layer of hardenable sealing compound, closing the mold by applying a bend-flexible cover so as to enclose the corrosion protection layer and the component, evacuating the mold so that the cover presses the component in the direction of the corrosion protection layer, and removing the vacuum and the cover after hardening of the sealing compound.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Further features, advantages and possible applications of the present invention arise from the following description of the exemplary embodiments and the figures. All features described and/or shown in the figures, alone and in arbitrary combination, form the subject of the invention, even independently of their combination in the individual claims or back references. In the figures, the same reference signs designate the same or similar objects.

[0026] FIG. 1 shows a sectional view of a system according to the invention.

[0027] FIG. 2 shows a top view of a system according to the invention.

DETAILED DESCRIPTION

[0028] FIG. 1 shows a schematic sectional illustration of the system 2 for applying a corrosion protection layer 4 to a surface to be protected of a component 6. The system 2 comprises a mold 8 which has a cavity 10 and a bottom face 12 arranged therein. The corrosion protection layer 4 lies on the bottom face 12. Said layer may for example be cut from a titanium sheet.

[0029] The component 6 is here for example an extruded aluminum profile with a double-T cross-section and an elongate extent. It has a surface 14 to be protected which, in later installation in a cabin of an aircraft, faces upwards and may be exposed to liquid soiling and condensation. In FIG. 1, the component 6 is oriented in the mold 8 with a top side 7 directed downwards and an underside 9 directed upwards.

[0030] The corrosion protection layer 4 has a flat, planar form with a very small material thickness, and is delimited by a first surface 16 lying flush on the bottom surface 12, and a second surface 18 arranged opposite this. The latter is bonded flush to the surface 14 to be protected of the component 6. For this, a hardenable sealing compound 20 is used which for example was applied to the surface 14 to be protected and/or the second surface 18 before insertion of the component 6 and corrosion protection layer 4. Due to an adhesion after application and before hardening of the sealing compound 20, and the joining of the two components 4 and 6, these initially tack together and can thereby be introduced into the mold 8 in the reverse orientation in order to begin a hardening process. After hardening of the sealing compound between the two components 4 and 6, a substance-bonded connection is formed by an adhesion to the boundary surfaces and cohesion of the sealing compound. Due to a cohesion after application of the sealing compound 20, and the joining of the two components 4 and 6, the two components tack together and can accordingly be introduced into the mold 8 in the reverse orientation.

[0031] The mold 8 has an edge 22 on which a capping 24 is arranged. This has a cutout 26 so that the entire capping 24 has a strip-like form following the edge 22. Between the capping 24 and the edge 22, a bend-flexible cover 28 is arranged which is situated above the component 6 and lies directly on the underside 9. The bend-flexible cover 28 may be connected to the capping 24 so that the two components form a single part.

[0032] By extraction of air from the cavity 10, a vacuum is created there which causes the bend-flexible cover 28 to lie flush against the component 6, and presses this in the direction of the corrosion protection face 4 or the bottom face 12. In order to fix the capping 24 to the mold 8, a row of quick-release clamps 30 is provided which can preferably be actuated manually without tools.

[0033] Sealing compound 20 which has been squeezed out of the sides of the component 6 may be used as a transition piece 32. Here it is conceivable that the hardened sealing compound 20 is later ground away.

[0034] FIG. 2 shows a top view of the system 2 with component 6 laid therein, and a corrosion protection layer 4 underneath. Here, the exemplary elongate form of the component 6 is visible. If shorter components 6 are introduced into the mold 8, intermediate walls (not shown here) may reduce the effective cavity 12 in order to allow simpler evacuation. End walls 34 could be removable and allow a combination of several molds 8. The mold 8 furthermore has a suction connection 36 at which a vacuum can be applied. An indicated extraction unit 38 is used for this.

[0035] In addition, it should be pointed out that the term “comprising” does not exclude other elements or steps, and the term “one” or “a” does not exclude a plurality. It is furthermore pointed out that features which have been described with reference to one of the above exemplary embodiments may also be used in combination with other features of other exemplary embodiments described above. Reference signs in the claims should not be regarded as a restriction.
