Definitions

  • the invention relates to a filling of a defect in which a layer of solder and a base material or material similar material is used to fill the defect.
  • the idea relates to a coating repair, in particular by means of laser beam build-up welding of components in combination with a solder material. Materials are used for this process. This is a material with a high proportion of intermetallic phase, e.g. Rene80 and a similar solder material. Fast build-up welding can rapidly switch back and forth between at least two streams of powder masses of different chemical composition, so that the chemical composition of the applied material changes seamlessly and no break in the powder mass flow into the molten bath occurs.
  • similar soldering materials in addition to the powder of the base materials can be used as filler metals for laser deposition welding.
  • the advantages are improved material properties of the component compared to conventionally welded components and an equal thermal expansion coefficient due to the same type of repair.
  • the figure shows a component 1 with a defect 4.
  • the component 1 may be any component of a metal.
  • the component is a high-temperature component, in particular a turbine, in particular a gas turbine, which then has a nickel- or cobalt-based superalloy.
  • defect 4 where there is too little material and must be replenished.
  • this is a trough.
  • the shape of the defect 4 is not restrictive, that is, a flank can also be open and have no side surface.
  • a substrate 14 of this component 1 has a certain base material, which has a certain melting point.
  • a solder material has melting point depressants such as boron (B), silicon (Si), germanium (Ge), magnesium (Mg), manganese (Mn) in addition to the base material or another composition which has a melting point which is at least 10K, in particular 20K lower relative to the base material.
  • melting point depressants such as boron (B), silicon (Si), germanium (Ge), magnesium (Mg), manganese (Mn) in addition to the base material or another composition which has a melting point which is at least 10K, in particular 20K lower relative to the base material.
  • the defect 4 is filled in layers and alternately with a base material or material similar to base material and a solder material. This starts, for example, with a layer or lower layer 10 'made of a solder material, on which the base material or the material similar to the base material is applied as a layer 11'. This is continued alternately until the defect 4 is completely filled and then provided with a filling 7.
  • the thickness of the individual layers 10 ⁇ , 11 ⁇ , 10 ⁇ ⁇ , 11 ⁇ ⁇ , ... can be different from each other and vary along the direction of the outer surface 17 towards.
  • the individual layers 10 ⁇ , 11 ⁇ , 10 ⁇ ⁇ , 11 ⁇ ⁇ , ... are means of a build-up welding process, in particular a powder-ver Huaweissch spavons generated more in particular a laser powder build-up welding process.
  • the individual webs are laid so that they are optimal for the subsequent load direction 20.
