Definitions
- the present invention relates to a mask for the kinetic cold gas compacting with a body for covering a non-coated portion of a substrate to be coated with a coating side exposed to the coating ff and a method for kinetic cold gas compacting in which a corresponding mask is used.
- the kinetic cold gas compaction or kinetic cold gas spraying is known from the prior art for coating materials and in particular also components of gas turbines or aircraft turbines.
- the kinetic cold gas compacting is described for example in US 5,302,414.
- the method is characterized in that the coating material is moved in the form of a powder with the aid of a carrier gas at high speed, but temperatures below the melting point of the coating material on the substrate to be coated, wherein the particles hit when the coating particles due to the high speed as well as the surface area of the substrate to be coated are deformed, so that there is a flow of the materials and an adhesion of the coating material on the substrate.
- conventional covers such as adhesive tape covers or silicone masks, such as those used in thermal spraying, for example, are not sufficient because they can not withstand the high particle speeds.
- the covering device is structurally
- the surface of the mask is formed so that the surface with the direction of impact of the particles forms an acute angle, so that the impinging particles do not adhere to the mask, but only deflected.
- the present invention is based on the finding that adhesion of the coating material, that is to say the particles which strike the substrate to be coated at high speed in the unmelted state, only takes place on the mask when the adhesion mechanism underlying the kinetic cold gas compacting can take place.
- adhesion of the coating material that is to say the particles which strike the substrate to be coated at high speed in the unmelted state
- both the impinging particles and the surface are plastically deformed in order to ensure that the materials flow into one another and thus adhere to the materials.
- the invention starts here and proposes a mask which is formed so hard on the side facing the coating source, ie the working side, that none of the kinetic cold gas compaction used Surface deformation, ie no plastic deformation of the working side can take place. This avoids that the surface material of the mask and the impinging coating particles deform and flow into one another and thus form an adhesive layer.
- the mask can either be formed so that a hard coating on the working side or a suitably formed edge region is present or that the mask is formed overall with a corresponding hardness, the mask then can be homogeneously formed over the thickness.
- a use or nitriding hardened steel or a corresponding hard material can be provided.
- the mask can be used and / or nitriding hardened on the working side. If the mask is not through-hardened, a steel suitable for use or nitriding would then be present in the area of the main body, while the surface area of the working side would have hardened accordingly.
- the hard material for forming the mask or forming a hard surface layer on the working side of the mask may be formed by diamond, diamond-like carbon, cubic boron nitride, silicon carbide, alumina, boron carbide, tungsten carbide, vanadium carbide, titanium carbide, titanium nitride and / or zirconia or combinations thereof be.
- the hard material may also be enriched in a corresponding surface.
- Cr 3 C 2 -NiCr, Co28Mol8Cr3.5Si (T800) or the like can be used as the material for the hard working side.
- Figure 2 is a cross-sectional view of a second mask according to the invention when used in kinetic cold gas compacting.
- FIG. 1 shows a cross-sectional view of a first embodiment of a mask 1 according to the invention, which has a main body 2, in which a through-opening 4 is provided.
- the passage opening 4 permits a coating in this area of the mask 1, while in the other areas 5 and 6 there is a shielding of the coating material with respect to a substrate to be coated arranged underneath the mask.
- the page designated by the reference numeral 7 of the mask 1 is the working side, ie the side facing the coating source.
- a coating 3 is provided, which is formed from a relative to the base body 2 harder material.
- the coating 3 is a hard material layer, such as, for example, a chromium-nickel steel hardened with chromium carbides or other suitable hard material layers.
- the mask 1 can consist of a case-hardenable or nitriding-hardenable steel, wherein the edge region 3 is hardened accordingly by case-hardening or nitriding.
- the working side 7 has a sufficiently high hardness in order to prevent the coating particles impinging on the mask from adhering to the mask 1.
- FIG. 2 shows a second embodiment of a mask 10 according to the invention, which is of homogeneous design, that is to say it has the same material over its entire thickness.
- this may be a through-hardened insert or nitriding steel.
- the mask 10 in turn has a passage opening 11 which defines the coating area for the substrate 20 arranged thereunder. Only in this coating area, which is defined by the fürgangsöffhung 11, a surface layer 21 is formed from the Beschichstungssto ff in the coating of the substrate 20.
- the coating material is accelerated by a non-illustrated device for kinetic cold gas compaction or kinetic cold gas spraying in the direction of the substrate 20, wherein of the corresponding device, only the nozzle 12 is shown.
- the particle beams 13 are prevented from entering the substrate 20 by the shading areas 15 and 16 of the mask 10. Due to the hard formation of the mask 10, no deformation of the particles on the hard working side 17 and thus no deposition of an adhesive layer will take place in the impact areas 14 of the particle beams 13.
