- 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 concerns one Coating, which large volume fractions, in the range of 20 to 90 vol%, to NiAl ⁇ phase in a ⁇ matrix contains.
- the coating material not only pre-base material Oxidation and corrosion protects, but also the mechanical properties of the base material.
- DBTT Ductile Brittle Transition Temperature
- a coating is described, which is a typical Ni-base superalloy (single crystal alloy) is with addition of yttrium and silicon. Although these elements improve creep resistance and lead also at a low ductile-brittle transition temperature, but the also contained elements W, Mo and the low levels of Cr and Co cause a harmful effect on the oxidation resistance.
- the ⁇ -phase of NiAl alloys has an ordered cubic B2 crystal structure (CsCl prototype) and consists of two simple interpenetrating cubic cells, in which the Al atoms are the cube corners of one sublattice and the Ni atoms are the Occupy cube corners of the other subgrid.
- the ⁇ -phase is coarse and therefore brittle.
- US Pat. No. 5,116,438 discloses .beta.-phase Ni aluminides which are reacted with gallium are microalloyed. These have a significant at about 0.25 atom% Ga Improvement of ductility at room temperature. A higher proportion of Ga acts are negative.
- the invention is based on the object, the ductility of NiAl coatings, which have a high proportion of ⁇ -phase in a ⁇ -matrix to improve.
- the ⁇ -phase can have a different composition, for example, NiAlCr, NiAlMo.
- the coating of a Ni-based alloy having an Al content which comprises a NiAl- ⁇ phase having a content of Contains NiAl- ⁇ in the range of 20 to 90% by volume in a ⁇ -matrix the following chemical composition (in% by weight) of the coating has: 13 Cr, 30 Co, 11.5 Al, 0.5 Ta, 1.2 Si, 0.3 Y, 0.1-8 Fe, and optionally 0.0005-0.9 B and / or 0.0005-1 Zr, and / or 0.1-8 Mo and / or 0.1-8 Ga, wherein the Total content Fe, Mo and Ga is 10% maximum, balance Ni and unavoidable Impurities.
- the advantages of the invention are that the ductility of the coating is significantly improved.
- micro-alloying with Fe and optionally with Ga and Mo is achieved by refining the ⁇ -phase and thus increasing the ductility is, without the oxidation resistance is reduced. Will the exceeded ranges, so the unfavorable effect on the Ductility and resistance to oxidation and corrosion.
- B 0.001-0.5% by weight
- Zr 0.001-0.5 wt .-%)
- C 0.5 wt .-%
- the comparative alloy VL 2 was microalloyed with Zr and Fe.
- the following alloy data in% by weight was prepared, at which the plastic deformation was also determined in a three-point bending test at 200 ° C.:
- Inventive alloy modified comparative alloy According to Tab. 1 Zr Fe L 21 VL 2 0.2 3
- the ductility of the NiAl- ⁇ phase can thus be determined coatings are increased.
- the microalloying elements refine the coarse ⁇ -phase.
- B, Zr and C consolidate the grain boundaries and the ⁇ / ⁇ phase boundaries.
- ⁇ / ⁇ -Phasengrenzenfestiger C and / or B can also be added. It is the addition of 0.0005 to 0.9, preferably 0.001 to 0.5 wt .-% B, 0.0005 to 1.0, preferably 0.001 to 0.5 wt .-% Zr and 0.0005 to 0.8 wt .-% C provided.
- phase boundary strengtheners B, C and Zr may be used singly or in combination be added.
