Definitions

  • the invention relates to a component, in particular a component of a gas turbine.
  • the invention further relates to an antioxidant coating for such a component and a method for producing the same.
  • EP 0 784 104 B1 relates to a nickel-based superalloy with an optimized platinum-aluminum coating.
  • an article having a platinum-aluminum surface area, a substrate having a nickel-based substrate composition and a substrate surface, platinum and subsequently aluminum being diffused into the substrate surface first, and thereby providing a substrate area which an integrated aluminum content of 18 to 24 wt .-%, an integrated platinum content of 18 to 45 wt .-% and in the rest components of the substrate composition.
  • the substrate area thus formed forms a protective layer for the substrate.
  • the integrated values of aluminum and platinum are determined by an integration method, the platinum content and the aluminum content being integrated over the distance from the outer substrate surface.
  • a lower integration limit is around 2-3 ⁇ m below the substrate surface.
  • An upper integration limit is determined by the distance from the substrate surface at which the aluminum content, measured in% by weight, has dropped to an amount of 18% by weight, starting from larger values. This upper integration limit is used both for the determination of the integrated aluminum content and for the determination of the integrated platinum content.
  • the platinum-aluminum surface area is provided by two diffusion processes carried out in succession. Due to the separate alitation, the production of such a surface area acting as a protective layer is time-consuming and expensive.
  • the present invention is based on the problem of proposing a novel component with a substrate area, a novel oxidation protection coating and a method for producing such a component. This problem is solved in that the component mentioned at the outset is further developed by the features of the characterizing part of patent claim 1.
  • the component has a substrate composition based on nickel with an aluminum content of greater than 4.5% by weight. Only at least one platinum group metal is diffused into the substrate surface of the component to form the substrate surface area.
  • the present invention is based on the finding that a substrate surface area serving as protection against oxidation can be provided in a component whose substrate composition based on nickel or nickel alloy has an aluminum content of at least 4.5% by weight, in that only at least one metal the platinum group, preferably exclusively platinum, is diffused into the substrate surface of the component.
  • a substrate area on the surface of the component has good oxidation resistance, and it can be produced more cost-effectively than substrate areas known from the prior art, in which a separate alitizing process is required after the platinum has diffused in.

  • the blade 10 has an airfoil 11 and a blade root 12.
  • the entire blade 10, that is to say both the airfoil 11 and the blade root 12 is in the region of a surface 13 of the blade 10 in order to provide oxidation protection coated.
  • the blade 10 forms a substrate for the coating for forming the oxidation protection on the surface 13 of the blade 10.

  • the platinum fractions in the substrate area given above are integrated fractions.
  • the integrated parts are determined using an integration method.
  • this integration method an integration is carried out over the distance d from the outer substrate surface, the platinum component being dependent on the distance or on the depth relative to the outer substrate surface.

  • x m j n 0 ⁇ m; in the case where the lower integration limit is formed by a point immediately below the substrate surface, Xmir is preferably 5 ⁇ m.
  • An upper integration limit x max is formed by the distance or by the depth with respect to the substrate surface, at which the proportion of platinum has dropped to 5% by weight and remains below this value.
  • the value of the integral is then divided by the difference between the upper integration limit x ma ⁇ and the lower integration limit x m i n , so that ⁇ p t -in t applies for the determination of the integrated platinum fraction:
  • the procedure is such that in a first step a corresponding component with a substrate surface and a substrate composition is provided, the substrate composition based on nickel having an aluminum content of at least 4.5% by weight. Only at least one platinum group metal is then diffused into a substrate surface of this component.
  • platinum and / or palladium is preferably diffused into the substrate surface, preference being given to the diffusion of exclusively platinum into the substrate surface. Platinum is diffused in using the slip technique. Accordingly, a corresponding platinum slip material is applied to the surface of the substrate and then cured.
