Definitions

  • FIG. 1 schematically shows a production method for producing a corrosion-resistant pressure vessel steel product 1 with a substrate 4.
  • the substrate contains or “indicates” means that the respective element is significantly above the detection limit and / or the degree of contamination in a metallic alloy, in particular at least the has twice the detection limit or impurity level, whichever is higher.
  • the aluminum-enriched layer 7 is preferably 80 ⁇ m thick. It is also possible to produce a chromium-rich layer instead of aluminum or particularly preferably to produce an aluminum-rich and chromium-rich layer 7.
  • the method is particularly suitable for internal coating of fuel-carrying channels: fuel supply, hub,
  • FIG. 5 shows a combustion chamber 110 of the gas turbine 100.
  • a ceramic thermal barrier coating may be present and consists for example of ZrO 2 , Y 2 O 3 -ZrO 2 , ie it is not, partially or completely stabilized by yttria and / or calcium oxide and / or magnesium oxide.

Abstract

Les aciers pour récipients sous pression présentent souvent une faible résistance à la corrosion. L'acier résistant à la corrosion pour récipients sous pression est obtenu par aluminisation d'un acier pour récipients sous pression et oxydation intentionnelle de la couche ainsi enrichie.
