- C23C30/00—Coating with metallic material characterised only by the composition of the metallic material, i.e. not characterised by the coating process
Definitions
- the invention relates to the field of materials technology. It affects one Coating which has large volume fractions, preferably in the range of 20 contains up to 90% by volume of NiAl- ⁇ phase in a ⁇ matrix.
- a large number of alloys are known which are used for coating e.g. B. gas turbine components can be used.
- the gas turbine components for example turbine blades, are exposed to high temperatures and should be protected against oxidation and corrosion by means of the coatings.
- the coating material Base material not only protects against oxidation and corrosion, but also that mechanical properties of the base material are not affected.
- a low ductile-brittle transition temperature ductile brittle Transition Temperature - DBTT
- a certain ductility at low Temperatures for the coating material can be reached.
- US Pat. No. 5,943,138 describes a coating which has a typical Ni-based superalloy (single crystal alloy) is with the addition of yttrium and silicon. Although these elements improve the creep resistance and lead also to a low ductile-brittle transition temperature, but the also contain elements W, Mo and the small proportions of Cr and Co cause a harmful effect on the resistance to oxidation.
- the high-strength NiAl alloys developed in recent years can to some extent compete with the Ni-based superalloys, however, is a Disadvantage compared to the ductile, high-tough Ni-based superalloys low toughness and its high DBT temperature (R. Dariola: NiAl for Turbine Airfoil Application, Structural Intermetallics, The Minerals, Metals & Materials Society, 1993, pp. 495-504), which results in a low ductility of this Alloys reflect at low temperatures.
- the beta phase of NiAl alloys has an ordered cubic B2 crystal structure (CsCI prototype) and consists of two simple interpenetrating cubic cells, at where the Al atoms are the cube corners of one sublattice and the Ni atoms are the Occupy the cube corners of the other subgrid.
- the ⁇ phase is rough and therefore brittle
- the object of the invention is to improve the ductility of NiAl coatings, which have a high proportion of ⁇ phase in a ⁇ matrix.
- the ⁇ phase can have a different composition, for example NiAl, NiAlCr, NiAlMo, NiAlTi.
- the phase containing NiAl- ⁇ Coating has the following microalloying elements (data in% by weight) 0.1-8 Fe and / or 0.1-8 Mo and / or 0.1-8 Ga, the total proportion Fe, Mo and Ga is at most 10%.
- the advantages of the invention are that the ductility of the coating is significantly improved.
- microalloying with Fe, Ga and Mo achieves that the ⁇ phase is refined and thus the ductility is increased without that the oxidation resistance is reduced.
- the specified Crossed areas this has an adverse effect on ductility and resistance to oxidation and corrosion.
- the coating is max. 4% by weight Fe, Ga, Mo contains.
- B 0.0005-0.9, preferably 0.001-0.5% by weight
- Zr 0.0005-1.0, preferably 0.001-0.5% by weight
- C 0.0005-0.8, preferably max. 0.5% by weight
- the comparative alloys VL 1, VL 2 and VL 3 were microalloyed with Zr, B, and Fe.
- the following alloys (data in% by weight) were produced, on which the plastic deformation was also determined in a three-point bending test at 200 ° C:
- Alloys according to the invention modified comparison alloys
- Table 1 Zr B Fe L 11 VL 1 0.2 0.05 4th L 12 VL 1 0.2 - 3rd L 13 VL 1 0.2 - 4th L 21 VL 2 0.2 - 3rd L 31 VL 3 0.2 - 3rd
- Fig. 1 shows the force-deflection diagram for the from the prior art Technology known comparison alloy VL 1.
- the sample showed only a small one plastic deflection and increased with a force of approx. 1 kN Fracture.
- Fig. 2 shows the force-deflection diagram of the inventive Alloy L 11 (comparative alloy VL1, micro-alloyed with 0.2% by weight Zr, 0.05% % By weight B and 4% by weight Fe).
- the sample showed one in comparison to VL 1 much greater plastic deflection and only increased at around 1.2 kN Fracture.
- VL 1 has a ductile-brittle transition temperature of greater than 300 ° C alloy
- L 11 has a significantly lower ductile-brittle transition temperature (200 ° C).
- alloy L 12 composition as L 11, but without the addition of boron and with only 3% by weight Fe
- FIG. 2 shows the force-deflection diagram 3 that compared to Fig. 2, the plastic deflection somewhat was lower, but the force at which the sample broke, at approx. 1.3 kN was slightly higher.
- microalloying with Fe, Zr and B the ductility of the NiAl- ⁇ phase can be reduced contained coatings can be increased.
- the microalloying elements refine the rough ⁇ phase.
- B, Zr and C strengthen the grain boundaries and the ⁇ / ⁇ phase boundaries.
- the three-point bending test was subjected to a force of about 0.9 kN and a deflection of about 1.65 mm to break.
- FIGS. 7 and 8 clarifies.
- the comparative alloy VL 3 went with a force of approx. 2 kN and a deflection of 1.7 mm to break while the Alloy L 31 according to the invention, which differs from VL 3 in that that it is additionally micro-alloyed with 3 wt.% Fe and 0.2 wt.% Zr Fracture had a deflection of approx. 2.2 mm.
- the plastic deformation and thus the ductility of the coating alloy could be decisive can be increased by adding these additional elements.
- the Ductilization of the NiAl phase slows crack propagation, i.e. H. the Crack toughness is increased, which has a positive effect on the stress behavior of the Coatings affects.
- the invention is not limited to that described Embodiments limited. It can be used on all ⁇ -phase NiAls Coatings are applied. Fe, Mo and Ga can each be in the Range of 0.1 to 8, preferably 4 wt .-%, are added. The Elements can be added both individually and in combination, with a Total share of max. 10% by weight should not be exceeded. The mentioned elements refine the ⁇ phase and thus increase ductility, without reducing the resistance to oxidation. Will the specified areas exceeded, this has an unfavorable impact on the ductility and Resistance to oxidation and corrosion.
- phase boundary hardeners B, C and Zr can be used individually or in combination be added.
