Definitions

  • the invention relates to a method for coating a component according to the preamble of claim 1.
  • the entire outer or inner surface of a component should not always be coated. This applies to all coating processes, e.g. Plasma spraying, PVD (physical vapor deposition) or CVD (chemical vapor deposition) processes.
  • Parts of the coating must be removed where no coating was desired. This often happens through an abrasive removal of the coating in these areas, since the material of the coating adheres very well to the component or even reacts with it, e.g. if the component was coated with aluminum to carry out an alitation.
  • the abrasive removal leads to damage or a change in the geometry of the component. This is e.g. in the case of sandblasting, in which the sand particles remove the aluminum from the component, for example.
  • US Pat. No. 6,036,995 shows the need for masking by adhesive tapes, metal foils. Coating is carried out by applying slip. Metal foils do not adhere well to a substrate and therefore offer insufficient protection in a vapor deposition system in which the particles to be applied move in all directions. Adhesive tapes cannot withstand high temperatures.
  • the object is achieved by a method according to claim 1.
  • the surface in which no coating is desired is at least partially protected by a ceramic powder.
  • FIGS. 4 and 5 further exemplary embodiments for the application of the method according to the invention.
  • FIG. 1 shows a component 1, in particular a turbine blade of a gas turbine, for example consisting of a nickel or cobalt-based superalloy, which has a surface 4.
  • the surface 4 of the component 1 is to be coated with a ceramic or metallic coating material 19, such as aluminum.
  • the mask 7 consists of a suspension, a slip or a paste of a ceramic powder, in particular zirconium oxide, which is applied to the component 1 by immersing the component in the suspension, brushing, spraying or other types of application. The application can take place locally or over a large area. The mask 7 does not react with the component 1
  • Masking 7 remains adhered to component 1 during the coating of component 1, for example due to the presence of an organic binder in the paste or suspension.
  • the component 1 is coated with the coating material 19 by means of a CVD process (chemical vapor deposition) or PVD process (physical vapor deposition) or plasma spraying. Other types of coating are conceivable.
  • Figure 2 shows the component 1 that has been coated. There are areas 25 on the surface 4 with a coating 13 on the component 1 where this is desired. There is also a coating 16 on the mask 7.
  • the mask 7 can be easily removed, for example because it adheres to the component 1 only through the organic binder, there is no impairment of the component 1 in the regions 10 in which no coating was desired (FIG. 3). ,
  • FIG. 4 shows a further application example for the method according to the invention.
  • the component 1 can also have a cavity 22 in which a mask 7 is applied.
  • the process is therefore also suitable for external and internal surfaces.
  • FIG. 5 shows a further application example for the method according to the invention.
  • a coating 13 is to take place in the cavity 22 of the component 1.
  • a coating of an outer surface 28 of the component 1 is not desired, so that a mask 7 is applied to the outer surface 28 of the component 1.
  • the entire component 1 with the masking 7 can be introduced into the coating process without coating in the area 10 in which no coating is desired, but only in the desired areas on an inner surface 31 of the component 1.
  • the inner surface can likewise 31 are partially protected by masking.
  • This is e.g. particularly useful for internal alitation of turbine blades for a gas turbine.
