Abstract: PROBLEM TO BE SOLVED: To provide a winding bar whose maximum electric field strength at an edge region is decreased, without making the thickness of an insulator large. SOLUTION: In a winding bar 10, which is for a high-voltage winding of an electric machine especially for a stator winding, has piled-up conductors 13 whose bundle has a rectangular cross section, and is surrounded by an insulator 14 around, an electric field strength improved at edges as a whole is achieved without changing the insulator thickness. This is performed by making a thickness d2 of the insulator 14 at an edge 15 of the winding bar 10 larger than the thickness d1 of the insulator 14 at a flat surface of the winding bar 10. In this case, it is preferable that a correcting process is performed for forming the edge regions.

Abstract: In a process for applying a metallic adhesion layer for thermally sprayed ceramic thermal barrier coatings (6) to metallic components (1), the surface which is to be coated being cleaned in a first process step, so that the metallic surface is free of grease and oxide, a binder (3) is applied to the metallic surface of the base material (2) in a second process step. Metallic adhesive powder (4) is applied uniformly to the binder (3) in a third process step and solder powder (5), which has a smaller particle size than the adhesive powder (4), is applied uniformly to the binder (3) in a fourth process step. After drying the binder (3), a heat treatment is carried out for the purpose of soldering. The adhesion layers produced in this way are rough and provide a considerable positive lock for the ceramic thermal barrier coatings (6) which are to be sprayed thereon.

Abstract: One or more sealing strips (18) are mounted on the rotary component (1). Opposite each strip is a wearing layer (17) on the fixed component (2), and from this a sealing strip (20) protrudes. The strips on the fixed component can alternate with those on the rotary one.

Abstract: The guide blade (1) has in the interior a hollow space (6) acted upon by vacuum and at least one opening, provided with a porous cover (7) having capillaries (11), for fluid suction in the region of the blade edge (4) situated downstream. A guide blade (1) is to be created which is provided with effective fluid suction which does not result in any reduction in the efficiency of the turbine. This is achieved when all capillaries of the porous cover (7) are filled with the fluid to be drawn off, and when a wall withstanding the application of vacuum is formed by the porous cover (7) and the liquid-filled capillaries (11). This wall is permeable to the fluid only where it is wetted by the fluid.

Abstract: A method of applying a metallic bonding layer for thermally sprayed ceramic heat insulating layers (6) on metallic components involves (a) applying a binder onto the degreased and oxide-free metallic surface of the substrate material (2); (b) applying metallic bonding powder (4) uniformly onto the binder; (c) applying solder powder (5), of smaller particle size than the bonding powder (4), uniformly onto the binder; and (d) drying the binder and heat treating to effect soldering. In an alternative method, an oxidation and corrosion resistant layer is produced on the cleaned metallic surface by gas-shielded plasma spraying prior to step (a), the bonding powder is a coarse powder having the same composition as this oxidation and corrosion resistant layer, step (c) is omitted and step (d) comprises drying the binder and then heat treating (solution annealing) to form a sintered bond between the metallic component and the oxidation and corrosion resistant layer and between the oxidation and corrosion resistant layer and the bonding powder. Also claimed are metallic bonding layers produced by the above methods.

Abstract: A coil rod (10) for a high-tension coil such as a stator coil in an electrical machine includes many conductors (13) fitted over or alongside each other forming a rectangular cross-section of conductors enclosed by insulation (14). Without changing the insulation thickness, electrical consistency on the edges is improved if the insulation thickness (d2) on the edges (15) of the coil rod is greater than the insulation thickness (d1) on the coil rod's flat sides.

Abstract: Guide blade in which all the capillaries (11) of the porous cover (7) are filled with extracted fluid. A wall which maintains the negative pressure effect in the cavity (6) is formed by the porous cover and the fluid filled capillaries. The cover may be made from a high porosity sintered material using a Cr-Ni-steel base, an X20Cr Mo-steel base, a bronze base (CuSn10) or a low pressure plastic base. The cover is joined to the blade by soldering, welding, adhesion and/or a mechanical pressing.
