On account of their form of coating, layer systems according to the prior art often only have a low level of attachment to the substrate. The layer may then become detached in the event of high mechanical loads being applied to the components. The layer system according to the invention has separately produced anchoring means which are more strongly attached to the substrate than the attachment of the layer to the substrate.

On account of their type of coating, layer systems of the prior art often exhibit poor adhesion to the substrate. If the components are subject to high mechanical stresses, the layer can then become detached. The layer system according to the invention has separately produced anchoring means which allow stronger attachment to the substrate than the attachment of the outer layer to the substrate.

Process and apparatus for producing a turbine component, turbine component and use of the apparatusTurbine components have to withstand high thermal and mechanical loads. It therefore proves advantageous for them to be made from a material with a preferred crystal orientation. Hitherto, the turbine components with a preferred crystal orientation have been produced as a single piece, with relatively high scrap rates. The proposed concept makes it possible to produce a preferred turbine component (9, 10) in a particularly simple way by assembling a turbine component (9, 10) at least from a first base part (1) and a build-up material (8), the subregion (7) of the joining zone having a preferred crystal orientation (2), so that disadvantageous properties of a joining zone without a preferred crystal orientation (2) which have hitherto been encountered are avoided.

Methods according to prior art for producing three-dimensional molded bodies generally require outer molds which define the geometry of a component to be produced. The inventive method for producing three-dimensional molded bodies renders one such mold redundant. The geometry of a component to be produced is defined by a pre-determined laser guidance or by the geometry of the partial quantities used.

In the case of the epitaxial growth according to the prior art, a number o strips often have to be produced in a plane in order to restore an area to be repaired. This leads to overlapping and misorientation of the crystalline structures. In the case of the method according to the invention, the strip is of such a width that no overlapping occurs, since the width is adapted to the contour of the area to be repaired.
