Definitions

  • the invention relates to a method for smoothing the surface a gas turbine blade, in particular a gas turbine blade with a corrosion protection layer.
  • DE-A-39 18 824 and US-A-5,105,525 show an iron soleplate, which is a particularly scratch-resistant, well slidable and easy to clean surface.
  • the soleplate is coated with a nickel hard alloy and in one Drag-sanding process ground and polished.
  • US-A-4,321,310 describes a process for producing a Coating described on a gas turbine blade.
  • the Gas turbine blade has a base made of a cobalt base or nickel-based superalloy.
  • an adhesion promoter layer of the MCrAlY type is applied on this basic material.
  • M denotes a combination, for example of the metals nickel and cobalt.
  • Cr stands for chromium and Al for Aluminum and Y for yttrium.
  • On this adhesive layer a ceramic layer made of zirconium oxide is applied, which grew up in the form of a stem, the stem directed essentially perpendicular to the surface of the base body are.
  • the adhesive layer is polished until there is a surface roughness of about 1 ⁇ m.
  • US-A-5,683,825 also discloses an application method a thermal barrier coating on a component of a gas turbine out.
  • Low pressure plasma spraying is applied to a base body a NiCrAlY adhesion promoter layer applied.
  • the surface of the adhesion promoter layer is polished, so that it has a surface roughness of about 2 ⁇ m having.
  • the bonding agent layer thus polished is coated with a vapor deposition process (PVD, Physical Vapor Deposition) a ceramic thermal barrier coating with yttrium stabilized Zirconia applied.
  • PVD Physical Vapor Deposition
  • the thermal barrier coating here with the so-called electron beam PVD process applied.
  • the thermal barrier coating can also by means of Plasma spraying can be applied.
  • US-A-5,498,484 also describes the application of a Thermal insulation layer on an adhesion promoter layer of a component described a gas turbine.
  • the average surface roughness the adhesion promoter layer is covered with at least 10 ⁇ m specified.
  • US-A-5,645,893 relates to a coated component with a Base body made of a super alloy and with a Adhesion promoter layer and a heat insulation layer.
  • the adhesion promoter layer has a platinum aluminide and one on it subsequent thin oxide layer.
  • the thin oxide layer has alumina. Bordered by this oxide layer the thermal insulation layer, which by means of the electron beam PVD process is applied. It is stabilized with yttrium Zirconium oxide applied to the adhesive layer. Before the adhesive layer is applied, the Surface of the base body using a coarse sandblasting process cleaned. For material removal processing of the Aluminum oxide sand is used for the base body.
  • the object of the invention is to provide a method for smoothing the Specify the surface of a gas turbine blade that is particularly useful efficient and cost effective way to a sufficient smooth surface of the gas turbine blade leads.
  • this object is achieved by specifying a Process for smoothing the surface of a gas turbine blade, in which the gas turbine blade with a towing device through an abrasive medium along a towing direction is being towed.
  • Figure 1 shows a gas turbine blade 1 with an airfoil 3, a platform 5 and a blade root 7.
  • the airfoil 3 has a pressure side 9 and a suction side 11 on an entry edge 13 and a trailing edge 12 contiguous.
  • the airfoil 3 is like that Airfoil 3 facing surface of the platform 5, with provided a corrosion protection layer 15.
  • the corrosion protection layer 15 is a metallic alloy of the class MCrAlY. Open on the surface 14 of the airfoil 3 Cooling ducts 17.
  • the gas turbine blade 1 contains a hot gas exposed to very high temperatures. Protection against corrosion and oxidation by the hot gas serves the corrosion protection layer 15.
  • ceramic thermal barrier coating 19 may be applied.
  • the corrosion protection layer 15 also serves as an adhesion promoter layer between the base of the gas turbine blade 1 and the ceramic thermal barrier layer 19.
  • the anti-corrosion layer 15 are smoothed. An efficient one and inexpensive smoothing process is based on Figure 2 explained in more detail.
  • the cooling medium 18 forms one protective cooling film on the surface 14.
  • FIG 2 shows a grinding device 21.
  • a first annular container 23 is a liquid grinding medium 27 filled.
  • second container 25 is a second liquid abrasive medium 29 filled.
  • the grinding medium 27 contains an emulsion Abrasive discs of a certain medium size.
  • the second grinding medium 29 contains second emulsion Abrasives that are smaller on average than the abrasives of the grinding medium 27.
  • a swivel arm 31 is arranged, which along a Swivel direction 32 is pivotable. Along the swivel direction 32 is the swivel arm 31 from a position above the first container 23 into a position above the second container 25 swiveling.
  • a towing device on the swivel arm 31 33 There is a towing device on the swivel arm 31 33 arranged.
  • This towing device 33 leads on a support arm 39, a gas turbine blade 1 through the Abrasive medium 27.
  • a first axis 35 of movement of the gas turbine blade 1 is a rotation of the Towing device 33 defined. Through this rotation around the The first turbine 35 is the gas turbine blade 1 along a Circular path 43 dragged through the first container 23.
  • a second axis 37 is caused by a tilting movement of the support arm 41 and then with the gas turbine blade 1 perpendicular to the defined by the rotational movement about the first axis 35 Drag direction 36 defined.
  • a third axis 39 for the Movement of the gas turbine blade 1 is defined by a Rotation of the support arm 41.
  • a large number can of course also be attached to the towing device 33 of gas turbine blades 1 are arranged so that a high throughput of gas turbine blades 1 can be achieved.
