Definitions
- the invention relates to a method for adjusting the number of phases of a PtAl layer of a gas turbine component, in particular a component of an aircraft engine, and to a method for producing a single-phase PtAl layer on a gas turbine component.
- Single-phase PtAl layers are already known, as are the two-phase layers PtAl layers.
- diffusion annealing is usually necessary after alitization in order to lower the Al and Pt concentrations to such an extent that a single-phase structure is formed.
- This structure has advantages in terms of its mechanical properties.
- the object of the invention is to create a possibility by means of which a single-phase PtAl layer can be produced in a simple and cost-effective manner. It would also be particularly desirable if a possibility could be created by means of which the phasing of a PtAl layer could be influenced or adjusted.
- a method for influencing, in particular adjusting, the number of phases of a PtAl layer for a gas turbine component, in particular for a component of an aircraft engine, which is particularly useful in the production of such a layer in the production or repair of such a gas turbine blank is carried out or should be carried out. It is provided that steps are carried out for producing a single-phase PtAl layer on the gas turbine component, which are assigned to a first group, and steps are carried out for generating a two-phase PtAl layer on a gas turbine component, which are assigned to a second group.
- the steps of the first group have the following steps: applying a Pt layer to the gas turbine component whose thickness is less than 4 ⁇ m; Diffusion annealing so that the platinum (Pt) diffuses into the base material of the gas turbine component; and Alitieren, and controlled so that an aluminum content (Al content) sets, the small is ner or equal to 23 wt .-%, preferably less than or equal to 22 wt .-% is, preferably less than or equal to 20 wt .-% is, preferably less than or equal to 18 wt .-%, preferably less than or equal to 15 wt. %, preferably less than or equal to 13% by weight, preferably less than or equal to 10% by weight.
- the second group includes the following steps: applying a platinum layer (Pt layer) to the gas turbine component, the thickness of this platinum layer being in the range of 5 ⁇ m to 8 ⁇ m, preferably in the range of 5 ⁇ m to 6 ⁇ m, is; Diffusion annealing so that the platinum diffuses into the base material of the gas turbine component; and alitating to produce the PtAl layer.
- Pt layer platinum layer
- the Alitieren for producing a two-phase PtAl layer on the gas turbine component is carried out in a preferred embodiment for a period of time which is in the range of 8 to 15 hours, preferably in the range of 11 to 13 hours.
- a method for producing a single-phase PtAl layer on a gas turbine component is proposed. This process is carried out in particular in the context of the manufacture or repair of such gas turbine components.
- the method comprises the following steps: applying a Pt layer to the gas turbine component whose thickness is less than 4 ⁇ m; Diffusion annealing so that the platinum diffuses into the base material of the gas turbine component; and Alitieren for producing a PtAl layer, and so controlled that sets an Al content which is less than or equal to 23 wt .-%, preferably less than or equal to 22 wt .-%, preferably less than or equal to 20 wt. %, preferably less than or equal to 18% by weight, preferably less than or equal to 15% by weight, preferably less than or equal to 13% by weight, preferably less than or equal to 10% by weight.
- the platinum layer which is applied to this gas turbine component for producing a single-phase PtAl layer on the gas turbine component, is applied with a thickness which is in the range of 1 to 2 ⁇ m.
- the diffusion annealing which is carried out for producing a single-phase PtAl layer on the gas turbine component in order to cause platinum to diffuse into the base material of the gas turbine component, via a Period is carried out, which is in the range of 0, 2 to 4 hours, preferably in the range of 0.5 to 2 hours.
- the Alitieren for producing a single-phase PtAl layer is performed on the gas turbine component over a period of time which is in the range of 3 to 11 hours, in particular in the range of 6 to 10 hours.
- the base material of the gas turbine component may be, for example, a nickel-based alloy or a cobalt-based alloy.
- Alitering for producing the single-phase and / or biphasic PtAl may be accomplished, for example, by CVD, e.g. in gas phase or in the powder packing process.
- the Pt layer can be applied, for example, galvanically or by sputtering or sputtering.
- the application of the Pt layer takes place by PVD or by CVD.
- the Pt layer is then diffusion annealed as usual.
- This diffusion annealing can be of relatively short duration (eg 0.5 to 2 hours).
- an alitization is applied in an advantageous embodiment.
- This alitization may be controlled to give a low aluminum content, such as an aluminum content of less than 20%, less than 20% by weight, or less than 22% and less than 22% by weight, respectively.
- the donor and the activator are adapted accordingly.
- the invention makes it possible-at least in an advantageous embodiment-to produce one with low production costs, since the platinum layer thickness can usually be lowered from 4 to 6 ⁇ m to approximately 1 to 2 ⁇ m, since there is diffusion heating to be performed after alitating can be omitted, which applies in particular for single-phase PtAl layer.
