Abstract: A method for manufacturing a workpiece 1, 2 uses a forming tool 4, 5 having a cavity 3. An embossing element 6 profiled on at least one surface is arranged on at least one surface of the forming tool 4, 5 for producing a surface structure, and with the profile of the embossing tool 6 is imparted to the surface of the workpiece 1, 2 during a forming process.

Abstract: A compressor blade 1 of a gas-turbine engine has a flow-exposed leading edge 2. A component 3, made of wear-resistant material and featuring a higher erosive wear resistance than the base material, is attached to at least part of a length of the leading edge 2 The component 3 forming the flow-exposed leading edge 2 is strip-shaped, has an essentially rectangular cross-section and, with reference to a sectional plane perpendicular to the radial direction, is arranged only on an inflow side of the compressor blade profile in a partial area of a sectional surface of the inflow area.

Abstract: A method for processing at least one surface element wherein at least one layer of a deformable, medium-tight material is respectively attached to each side of the surface element, inserts the surface element and attached deformable layers between at least two molding tool parts and applies a pressure to at least one area of a surface section of the inserted surface element in response to a predetermined shaping temperature by introducing a medium between one of the deformable layers and a first molding tool part. The pressure acts directly against the deformable layer so that the surface element together with the deformable layers is shaped into at least one adjacent cavity of a second molding tool part due to the pressure created. A possibility of molding surface elements, which can currently not be shaped via gas pressure, into complex geometries, namely into spatially bent geometries, is created with this method.
