Definitions

  • the invention relates to a coating method in which a first layer is applied and this is converted by remelting.
  • Cold gas spraying is a coating process in which the coating material is applied to a substrate in powder form at a very high speed of 1000m / s to 2500m / s.
  • a process gas heated to a few hundred degrees is accelerated to supersonic speed by expansion in a Laval nozzle and then the powder particles are injected into the gas jet.
  • the injected powder material is thereby accelerated to such a high speed that it forms a relatively dense and firmly adhering layer in comparison with other thermal spraying methods, even without a preliminary onset or melting on impact with the substrate.
  • the kinetic energy at the time of impact is not sufficient for complete melting of the particles so that there is no metallurgical bond with the base material.
  • Laser remelting is characterized by exact energy input into a material, so that a desired remelting depth can be set exactly. Due to the large cooling rates and the spatially small melt volume during laser beam remelting, the solidification processes are primarily initiated by a nucleation favored by the melt pool edge. As a result, pores in particular are removed from the remelted areas and, in the case of nickel-base superalloys, the microstructure freezes virtually without pores. In addition, special microstructures can be set by the locally large heat gradients.
  • the object is achieved by a method according to claim 1.
  • the advantage of the invention allows a large-scale coating and local remelting at locations where only certain improved material properties are desired.
  • the figure shows schematically the procedure of the method.
  • thermal spraying / cold gas spraying By means of thermal spraying / cold gas spraying, a layer layer is applied to a base material. Subsequently, the layer is remelted by remelting so that either a metallurgical connection to the base material is achieved and / or special microstructural properties are set.
  • gradient layers can also be built up.
  • a component 1 is produced.
  • the component 1 is preferably a turbine component and has a substrate 4 preferably made of a nickel- or cobalt-based superalloy.
  • a first layer layer 7 ' is applied by means of a material jet 10.
  • cold gas spraying or other thermal spraying methods such as HVOF, LPPS, APS, VPS, PLC, SPPS.
  • cold gas spraying is mentioned below.
  • a further cold gas-sprayed layer layer 7 can be applied to the remelted layer 16, which is then again remelted 7".
  • the underlying layer layer 7 'in particular only partially melted in an upper area with.
  • the remelting can take place over a large area, i. the complete layer layers 7 ', 7 "are remelted or only a local remelting takes place at locations where certain material properties are desired, such as, in particular, freedom from pores or a certain hardness or a certain grain structure, which have better creep properties.
  • the heat-relevant property can be improved in a certain direction.
