Definitions

  • the invention relates to a layer system in which the substrate and the coating are rounded off in the region of the edge
  • Components are often coated to protect them from corrosion
  • turbine blades which have a blade platform which is also coated and has a side surface below the edge in the area of the blade platform that is nearly perpendicular thereto and uncoated.
  • the object is achieved by a layer system according to claim 1.
  • a coated fillet does not cause any cracks between the interfaces of the layers or the substrate.
  • FIG. 2 shows a layer system according to the invention
  • FIG. 3 shows a turbine blade
  • FIG. 4 is a list of superalloys. The figures and the description represent only embodiments of the invention.
  • FIG. 1 shows a layer system 1 according to the prior art.
  • the layer system 1 has a substrate 2, in particular made of nickel- or cobalt-based superalloys, in particular an alloy according to FIG. 4.
  • First and second surfaces 13, 20 are perpendicular to each other.
  • the second side surface 20 has no coating.
  • the layer 4 is preferably metallic, more preferably a NiCoCrAlX layer.
  • a ceramic layer 7 is applied, which represents the outermost layer.
  • the metallic layer 4 and / or the ceramic layer 7 may be formed in two layers as a metallic layer or as a ceramic layer.
  • an oxide layer of the metallic layer is present only during operation of the layer system or in advance.
  • FIG. 2 shows a layer system 1 'according to the invention.
  • the substrate 2 ' has alloys comparable to the prior art, a modified first surface 13' and a changed second side surface 20 ', since here a rounding 11 exists directly between the first surface 13' and the second side surface 20 'of the substrate 2' is.
  • a plane 21 of the first surface 13 'and a plane through the second surface 20' form a cutting line 27.
  • the metallic coating 4 'thus has, in contrast to the prior art, a region 5, which is below the plane 21, which is determined by the first surface 13', and on the material of the coatings 4 ', 7' is present and in which the at least one layer 4 ', 7' is arranged in the shortest connection from a cutting line 27 to the substrate 2 '.
  • the layer 4 'or layers 4', 7 ' run at its end in the region of the end 24 of the rounding 11 pointed.
  • the further layer 7 ' also has a portion 8 which is below a plane 22 which is defined by the surface 13' 'of the layer 4', but this portion is necessarily made thinner with comparable layer thicknesses with respect to the stand of the technique.
  • the ceramic layer 7 ' preferably also has a portion 30 below the plane 21. Thus, on the modified side surface 20 ', 11 there is no more perpendicular boundary surface and cracks are hardly initiated.
