Definitions

  • the invention relates to a protective coating for a thermally stressed component, in particular turbine component, for protection against corrosion and / or oxidation and / or erosion.
  • Turbine components in particular turbine blades, are in operation of the turbine exposed to corrosive and / or oxidative and / or erosive media.
  • the turbine components consist regularly of materials related to the in operation mechanical loads occurring on the turbine are optimized. These materials, which are based on nickel-based alloys, for example, are relative susceptible to corrosion, oxidation and / or erosion.
  • Usual basic materials for turbine components, especially for turbine blades, are: CM 247, CMSX 4 and IN 738.
  • a protective coating consist of a metallic, crystalline material that is usually used alongside others sufficient chemical elements in the aluminum components and contains chrome.
  • the aluminum provides the desired protection against oxidation, gradually on the outer surface of the protective coating a protective aluminum oxide layer grows up.
  • the alloying element supports this Chrome the formation of the protective aluminum oxide layer.
  • the life of such a protective coating is limited because the protective aluminum oxide layer continues to grow, causing the protective coating more and more aluminum is removed. With that way decreasing aluminum content of the protective coating reduces its strength and therefore their lifetime. By damaging the protective coating the lifespan for the item to be protected is also reduced Component.
  • the invention seeks to remedy this.
  • the present invention deals with deal with the problem for a protective coating of the type mentioned to specify an embodiment that has an increased lifetime.
  • the protective coating a single-layer or multi-layer sealing coating made of an amorphous material.
  • the invention is based on the general idea of the advantageous properties an amorphous structure in materials that protect against Corrosion and / or oxidation and / or erosion are suitable for manufacture a long-lasting protective coating.
  • Amorphous materials or amorphous structures are characterized by a low thermal conductivity, low diffusion speeds as well as high hardness and high thermal Stability.
  • the realization of these properties according to the invention in a corrosion-resistant and / or oxidation-resistant and / or erosion-resistant Material leads to a protective coating with a longer service life.
  • the invention uses the knowledge that the weak points of a conventional Protective coating or the weak points of the component surface are at the grain boundaries at which neighboring crystals of a crystalline Border structure together. For example, there is in the grain boundaries an increased concentration of alloy impurities, as a rule are susceptible to corrosion, oxidation or erosion. Except for monocrystalline Structures always have a large number of crystalline materials on the outside of these grain boundaries that are exposed to the aggressive media. in the In contrast, an amorphous structure has no grain boundaries, which means local Concentrations of impurities and thus weak points in the amorphous sealing coating can be avoided. The amorphous structure the sealing coating thus offers the aggressive media fewer points of attack and therefore has an increased lifetime.
  • such a sealing coating can be of high quality and goodness are produced, which in particular have no holes or gaps having. This can cause diffusion of aggressive atoms or molecules into the Sealing coating into or through the sealing coating be slowed down. Unlike a naturally growing one Aluminum oxide layer in which there are gaps between the crystals that form or holes can occur, this results in a further improvement in Protective effect and thus the lifetime of the protective coating and ultimately of the coated component.
  • the sealing coating on the Be arranged surface of the component hinders the transport of aggressive molecules or atoms, e.g. Oxygen, to the component, so that a long service life is guaranteed for the component can be.
  • aggressive molecules or atoms e.g. Oxygen
  • the protective coating can be in addition to Sealing coating a single-layer or multi-layer component coating Made from a crystalline material that is on the surface of the component is arranged, the sealing coating then on the Component coating is arranged.
  • This component coating can, for example from a conventional protective layer with a crystalline material exist, e.g. B. made of a nickel-based alloy.
  • a such component coating does provide relatively high-quality protection against corrosion, Offer oxidation and erosion, however, due to the free grain boundaries a relatively short lifetime. Due to the sealing coating applied to it are the grain boundaries of this component coating before a direct one Attack protected by the aggressive media, thereby extending the lifetime of this Coating significantly increased.
  • the protective coating according to the invention can additionally a single-layer or multi-layer thermal insulation coating have, which is arranged on the sealing coating.
  • a thermal insulation coating With the help of such a thermal insulation coating, the temperature exposure the sealing layer as well as the component and - if available - also the (conventional) component coating can be reduced. For example thereby necessary mechanical properties of the base material of the Component are guaranteed.
  • Such a thermal insulation coating can, for example consist of stabilized zirconium oxide.
  • the sealing coating is applied to one single-crystal or directionally solidified material applied.
  • FIGS. 1 to 4 one that is only shown in regions Component 1, for example a turbine blade, on its outer surface 2 with a protective coating 3 according to the invention for protection against Corrosion and / or oxidation and / or erosion can be coated.
  • This protective coating 3 has a single-layer or multi-layer sealing coating 4, which are made of an amorphous material or from a material with an amorphous structure.
  • the amorphous sealing coating 4 can from an amorphous metal, from an amorphous transition metal, from one amorphous metal alloy or from an amorphous non-metallic compound or combinations of these materials.
  • Sealing coating 4 made of an aluminum oxide-based or silicon carbon nitride-based Material or from a yttrium oxide-containing or cerium oxide-containing Material.
  • the sealing coating is used to achieve high stability 4 is preferably made relatively thin, i.e. their extension or Thickness perpendicular to the surface 2 of the component 1 is relatively small.
  • the thickness of the sealing coating 4 is less than 20 ⁇ m.
  • An advantage for the sealing coating 4 is a thickness of approximately 0.1 ⁇ m to 10 ⁇ m.
  • the amorphous sealing coating 4 a material is used that is in itself a sufficient thermal Stability as well as sufficient corrosion resistance and / or oxidation resistance and / or has erosion resistance.
  • the protective effect of such Material is significantly improved by the proposed amorphous structure.
  • the protective coating 3 in a first Embodiment exclusively from the sealing coating 4, the is accordingly arranged directly on the surface 2 of the component 1.
  • the Sealing coating 4 for example made of amorphous aluminum oxide or made of amorphous silicon carbon nitride, for example by a physical Steam coating process (“PVD process”) or by a chemical Damf coating process (“CVD process”) applied to component 1 become. Laser PVD processes or laser CVD processes are preferred here. Due to the sealing coating 4, the material of the Component 1 effectively protected against exposure to aggressive media, whereby the component 1 has an increased service life.

While the sealing coating 4 on is arranged on the surface 2 of the component 1, there is the thermal insulation coating 5 on the sealing coating 4.
  • the thermal insulation coating 5 can consist, for example, of a stabilized zirconium oxide, conveniently by air plasma spraying, flame spraying or by an electron beam PVD process is applied in one or more layers.
  • the temperature of the sealing coating 4 and the component 1 can be reduced, for example certain required mechanical properties, e.g. Stability, rigidity, Stretch behavior, the sealing layer 4 and the component 1 ensure can.
