Definitions
- Gamma, gamma ⁇ cobalt-based alloys for additive manufacturing or soldering, welding, powder and component
- the invention relates to a ⁇ , ⁇ x cobalt-based superalloy, which is used in additive manufacturing processes (AM) or in the brazing or welding of high-temperature components, a powder and a component.
- Y x- hardened nickel-based alloys are known from high-temperature use, as in gas turbines. Nickel-based alloys are subject to hot gas corrosion and can only be laboriously repaired due to their brittleness.
- Cobalt based alloys are known to have better properties in this regard.
- the disadvantage here is the poorer mechanical properties, due to an unstable Y x phase (Co, Ni) -3Ti.
- Additive manufacturing processes and soldering or welding are known from the prior art and are also used or developed for Y x -hardened nickel-based alloys.
- a precipitation-hardening cobalt-based alloy ⁇ the additive can be applied to production and during soldering or welding.
- An advantageous composition is Co-7W-7Al-23Ni-2Ti-2Ta-12Cr-O, 01B-0, IC- (0-0, ISi).
- the oxygen particle pressure during the processing must be precisely controlled.
- the proportion of tungsten (W) is kept rather low because of the density.
- the proportion of aluminum (AI) is rather kept low in order to reduce the weldability and oxidation affinity due to the ⁇ ⁇ content.
- the content of nickel (Ni) is kept high in order to extend the stability range for the ⁇ phase in combination with chromium (Cr).
- the proportion of titanium (Ti) is kept rather low due to the oxidation affinity.
- tantalum (Ta) is in the central region supported ⁇ th, also by the proportion of tungsten (W) in the Y x phase to replace and with the elements boron (B) and silicon (Si) to consolidate the grain boundaries.
- the proportion of chromium (Cr) is kept high in order to ensure good oxidation and hot gas corrosion resistance.
- the alloy is preferably subjected to a two-stage heat ⁇ treatment:
- a further advantageous heat treatment is solution annealing and elimination of ⁇ ⁇ in a two-stage heat treatment with temperatures at 1423K and 1193K.
- the alloy can be in powder form and also as
- Welding filler be used.
- This powder may contain ceramics or other admixtures as an ingredient.
