Definitions
- Gas turbines such as aircraft engines or stationary gas turbines, are subject to high mechanical and thermal stress during operation. Due to the stress during operation, in particular due to thermal cycling, erosion and the like, the components of gas turbines, in particular the blades exposed to the gas stream, may be damaged. By way of example, thermal fatigue cracks, eroded surfaces and the like are mentioned here. Since the components are made of high-quality and therefore expensive materials and must be produced by complex manufacturing processes, an exchange of correspondingly damaged components is not economical, so that during the maintenance and repair of gas turbines, especially aircraft engines, the components must be repaired. For this purpose, according to the state of the art, soldering processes are used in addition to welding processes. DE 10 356 562 A1, DE 10 2004 018 668 A1, EP 1 859 880 A1 or US Pat. No. 4,830,934 and EP 1 689 897 B1 disclose corresponding solder alloys.
- the first solder material is present in the mixture of the solder alloy in a proportion of 15 to 30 wt.%.
- the second solder material is also a nickel-based material, which has as alloying constituents chromium, cobalt, molybdenum, tungsten, boron and hafnium.
- the second solder material is present in a proportion of 15 to 25 wt.% In the mixture.
- the proportion of the first soldering material in the mixture may have 20 to 25% by weight and / or the proportion of the second soldering material may have 18 to 22% by weight.
- the corresponding alloy constituents in the first solder material and the second solder material Due to the suitable choice of the corresponding alloy constituents in the first solder material and the second solder material, it is possible in particular in combination with the proportion of the base material, which can correspond to the material to be soldered, a suitably suitable property profile of the solder alloy and adjusted to the application composition, the individual alloy components by training hardening phases z. B. (carbides) affect the strength properties or how, for example, boron act favorably on the melting point of the solder alloy. Other alloying constituents such as yttrium and hafnium can favorably influence the wetting behavior and flowability of the molten solder alloy. The oxidation resistance of the soldered rich becomes z. B. increased by aluminum.
- the first solder material may contain 10 to 20% by weight of chromium, in particular 13 to 16% by weight of chromium, 5 to 15% by weight of cobalt, in particular 9 to 11% by weight of cobalt, 2 to 4% by weight of tantalum, in particular 2, 5 to 3.5% by weight of tantalum, 3 to 4% by weight of aluminum, in particular about 3.5% by weight of aluminum, 2 to 4% by weight of boron, in particular 2.5 to 3.5% by weight of boron and 0.05 to 0.15 wt.% Yttrium and the balance nickel.
- the second solder material can contain 2 to 4% by weight of chromium, in particular 2.5 to 3.5% by weight of chromium, 3 to 7% by weight of cobalt, in particular 5 to 6% by weight of cobalt, 0.5 to 1.5% by weight % Molybdenum, in particular 0.9 to 1.1% by weight molybdenum, 5 to 10% by weight tungsten, in particular 7 to 8% by weight tungsten, 0.1 to 1% by weight niobium, in particular 0.2 to 0 , 5% by weight of niobium, 0.1 to 1.5% by weight of aluminum, in particular 0.5 to 1% by weight of aluminum, 2 to 4% by weight of boron, in particular 2.5 to 3.5% by weight of boron and 0, 5 to 1.5 wt.% Palladium, in particular 0.75 to 1.25 wt.% Palladium and the remainder nickel.
