  • thermal spraying encompasses completely different spraying methods, such as plasma spraying, arc spraying, laser spraying, flame spraying. Details on different spraying processes can be found in DIN 32530. Attention should also be drawn to high-speed flame spraying, detonation spraying and cold gas spraying.
  • thermal spraying The various spraying methods which fall under the term of thermal spraying have in common that a material to be applied to an object is fed to a device for thermal spraying, and that it is supplied there with thermal and kinetic energy.
  • the starting material typically a multicomponent powder
  • a gas which can also be ionized (in plasma spraying), creates a beam that directs the material to an object to be coated.
  • Thermal spray processes are used in particular in engine construction. Thermal spraying processes are used both for engine new production and for engine repair. Thermally sprayed coatings form in engine construction in particular corrosion and / or oxidation protection layers, erosion protection layers, dimensional correction layers, wear protection layers or titanium fire protection layers. However, correspondingly produced layers also form scrubbing or thermal barrier coatings. In addition to the advantages of using thermal spraying methods, however, there is also the disadvantage that components which are not to be processed have to be protected from erosion phenomena and undesirable thermal stresses by means of complex covering means, such as metal masks or plastic silicone compositions. A simple and quick handling of these methods is therefore not possible. In addition, known masking tapes, which in principle can be easily and quickly applied, can not be used, since they are eroded away during thermal spraying.
  • a masking adhesive tape according to the invention in particular for use in thermal spraying methods, comprises a band-shaped or strip-shaped carrier layer and an adhesive layer, wherein the carrier layer consists of silicone and a glass fiber and / or glass fabric insert and also has at least two flakes on the surface of the masking tape opposite the adhesive layer. or lamellar elements of metal or a metal alloy are attached to the carrier layer.

  • the use of silicone in the carrier layer also ensures that the Abdecklebeband is elastic enough to absorb the forces of relatively rigid scale or lamellar elements.
  • the masking tape according to the invention has the advantage that the masking tape between the slats can be easily divided by the flake or lamellar arrangement of the metal elements, also this structure also provides the necessary flexibility of the masking tape.
  • the adhesive layer may be formed from a silicone adhesive.
  • the scaly or lamellar elements may be made of steel, in particular a steel sheet.
  • the flake-like or lamellar elements are arranged such that they overlap at least partially. This prevents spray or material particles from penetrating against the scale direction and destroying the carrier layer.
  • the scaly or lamellar elements may also be formed magnetized, wherein the individual elements are arranged such that the north pole of an element always rests or rests on the south pole of the nearest element. Also by this measure, the individual elements form a relatively firm and closed protective layer against the penetration of said spray particles and counteract a possible destruction of the carrier layer.
