Definitions

  • the invention relates to a method for producing a corrosion and oxidation resistant Slip.
  • US 3,741,791 discloses slip coating superalloy substrates, preferably made of Ni or Co-based alloys, whereby to improve the corrosion and oxidation resistance a slip of Si powder and FeCrAlY powder manufactured, applied to the substrate surface, dried, and finally is heat treated at a temperature of about 1200 ° C.
  • FR 2 115 147 A describes a coating process for substrates made of Ni or Co-superalloys, which to improve the oxidation resistance in one dispersed mixture metal powder present, the particle size preferred is smaller than 38 ⁇ m, provided with a binder, applied to the substrates and then heat treated.
  • Co-Al, Ni-Al and / or Fe-Al plus Cr-Al alloys which can be pre-alloyed with Y.
  • Metal powders made of Fe, Ni or Co can optionally be mixed in.
  • WO 94 07004 A discloses the coating of substrates made of superalloys, in particular Ni-based alloys, with a slip, the slip material to improve the hot gas corrosion resistance Al and Si or Cr and Al in a dispersed mixture, applied to the substrate, dried and heat treated at 850 ° C to 1120 ° C in an inert atmosphere or in vacuum becomes.
  • a corrosion and oxidation protection layer is a metal powder by plasma spraying or the like Component applied. The layer is then subjected to an alitation and finally glowed.
  • the object of the invention is a method for producing a slip layer to create the genus described at the outset as simply as possible and is inexpensive to carry out.
  • An advantage of the method according to the invention is that by mixing an effect similar to that of e.g. in the classic Alitation of plasma-sprayed layers occurs, which is relatively expensive Plasma spraying and the alitizing process, however, are no longer necessary.
  • the method according to the invention can be used both for the production of protective layers on new and on repair parts deploy.
  • M comprises at least one element Ni or Co.
  • Both the starting and the addition powder have a grain size distribution from 5 to 120 ⁇ m.
  • the slip material is preferably brushed through with a brush Dipping or another suitable method applied to the component, whereby significant cost advantages can be achieved compared to plasma spraying.
  • the slip layer becomes heat-treated for about 2 hours, preferably in a protective gas atmosphere, e.g. can be carried out in argon, or in vacuo.
  • the addition powder preferably makes up to 35% by weight of the total wipe from starting powder and addition powder.
  • the starting powder made of MCrAlY and the added powder made of Al.
  • the M stands for the MCrAlY a mixture of Ni and Co. 75 % By weight MCrAlY and 25% by weight Al based on the total weight from starting and added powder mixed.
  • An inorganic binder is also admixed or a binder solution, e.g. a 30% chromium phosphate solution.
  • the slip material mixed in this way is applied to produce the slip layer a component that is to be protected against corrosion and oxidation, e.g. a Turbine blade of a gas turbine, applied with a brush.
  • the component can e.g. consist of a super alloy based on nickel and cobalt. Because of the inorganic binder is cured at 350 ° C.
  • the slip layer is heat-treated at a temperature of 1060 ° C, to achieve diffusion of the slip layer into the component.
  • the Heat treatment is carried out in an argon atmosphere for 2 hours. Depending on the application the heat treatment could alternatively also be carried out in vacuum or in a Normal atmosphere.
