Definitions
- the invention relates to a for hot gas designed product with a coating, in particular a gas turbine blade.
- the invention further relates to a Process for producing a coating for one for one Product designed for hot gas application.
- the aim of the research is to develop a diffusion barrier between the base material and the coating, which at the same time guarantees a good connection of the coating to the base material.
- This is achieved using a chrome-aluminum-oxide-nitride system (Cr-AL-ON).
- the object of the invention is to provide one for hot gas application designed product, in which one regarding their long-term durability improved coating is provided. Another object of the invention is to provide of a method for producing a coating for a Product designed for hot gas application.
- a hot gas product is often with a Provide protective layer of the type just mentioned.
- Such Protective layer serves to protect against oxidation and corrosion.
- Such a protective layer forms on contact with Oxygen is an oxide layer consisting essentially of aluminum oxide and / or chromium oxide.
- the oxide layer can also by oxidation of a thin layer applied to the protective layer Location of an oxide former, e.g. Aluminum or Chromium formed.
- the protective layer becomes poorer over time of aluminum and chrome in that aluminum and / or chromium diffuse into the oxide layer and oxidize there. As a result, the oxide layer grows. This is usually the case the life-limiting aging process for the coating and affects the mechanical properties of the growing oxide layer.
- the invention is based on the surprising finding that sufficient amounts of chromium nitride in the protective layer can be formed if the concentration of chromium exceeds 15 wt%, is preferably above 20 wt%.
- the chromium nitride acts as one particularly efficient diffusion barrier for diffusion from aluminum and / or chrome to oxygen. With that the Long-term durability of the coating significantly improved.
- the protective layer preferably contains rhenium, in particular with a proportion between 1 wt% and 15 wt%.
- rhenium in particular with a proportion between 1 wt% and 15 wt%.
- wt% by weight and at% atomic percent.
- the chromium nitride is preferably contained in the oxide layer.
- the chromium nitride is more preferably in a concentration between 10 at% and 60 at%, in particular about 50 at%.
- the chromium nitride is preferably between the Protective layer and the oxide layer present, preferably in a transition area or anchoring area between Oxide layer and protective layer.
- chromium nitride in the form of a To form a grid.
- the chromium nitride preferably forms one Grid, in particular an approximately rectangular grid a side length between 0.1 ⁇ m and 10 ⁇ m.
- the formation of a such a grid provides a particularly efficient diffusion barrier
- the lattice structure makes it susceptible to cracking the coating is reduced, which is additional improves the long-term durability of the coating.
- the product is preferred as a turbine blade, in particular designed as a gas turbine blade.
- Gas turbine blades are mostly particularly high thermal loads today and an intense attack by oxidation or corrosion exposed.
- the life span of the coating of a gas turbine blade usually determines the revision interval the whole shovel.
- the product is as Heat shield of a thermal machine, especially for one Combustion chamber, executed.
- a ceramic thermal barrier coating is preferred on the oxide layer applied, in particular a thermal barrier coating Zirconium base.
- a ceramic thermal barrier coating is used for Protection of the turbine blade from very high temperatures.
- the Ceramic thermal insulation layer is on the oxide layer to the Protective layer coupled.
- An increase in the oxide layer leads to increasing brittleness of the oxide layer.
- the increasing Brittleness of the oxide layer has long-term resistance the coating reducing effect by a increased susceptibility to detachment of the thermal barrier coating.
- Chromium nitride slows down the growth of the oxide layer, the long-term durability of the coating on a particularly vulnerable point, namely the boundary layer between Thermal insulation layer and protective layer improved.
- the nitrogen is preferably supplied from a nitrogen plasma source about a nitrogen plasma treatment. More preferred a nitrogen plasma is added to the coating, which also contains hydrogen as an oxygen getter.
- the supply of hydrogen in non-molecular Form enables oxygen to be extracted from the chromium oxide. This allows nitrogen to attach to the chrome, which leads to the formation of chromium nitride.
- BIAS nitrogen plasma source DC voltage
- one DC voltage from 50 V to 600 V, in particular from 100 V to 300 V applied.
- rhenium or other additives can be contained his.
- a ceramic thermal barrier layer 7 e.g. out Yttrium-stabilized zirconium oxide.
- Chromium nitride 6 is installed in the oxide layer 5 Chromium nitride 6 is installed. The chromium nitride 6 reduces the Diffusion of aluminum or chrome from the protective layer 4 in the oxide layer 5. This slows down the growth of the Thickness of the oxide layer 5. Since a thick oxide layer 5 becomes a leads to an increased risk of detachment of the thermal insulation layer 7, with the slowing of the growth of the oxide layer 5 the long-term durability of the coating 3 increases.
- a grid 8 made of chromium nitride 6 is shown schematically shown, which is made up of grid cells 7A.
- the The interior of the grid cells 7A consists of aluminum oxide and / or Chromium oxide.
- the grid 8 is not geometrically perfect, thus points e.g. Interruptions, changing thicknesses and changing area sizes of the grid cells 7A.
- Such a lattice of chrome nitride 6 is particularly efficient in preventing aluminum from diffusing or chrome.
