Abstract (en)
[origin: WO2007140748A1] The invention relates to a method of producing or repairing single-crystalline turbine or engine components, in which a braze filler metal is heated to a temperature which is greater than or equal to the melting temperature of this braze filler metal. The molten mass, thus produced, of the braze filler metal is then introduced into a crack formed in the turbine or engine component or into a gap formed between two turbine or engine components. The temperature of the braze filler metal is then controlled in a non-isothermal manner during an epitaxial solidification process of this braze filler metal. This method, which can be used, for example, in connection with turbine or engine components made of a nickel-base alloy, has the advantage over conventional methods that it permits a quicker brazing repair of turbine or engine components, in particular in the case of large gap or crack widths, and in addition this method can bring about a state in which the repaired regions again have a single-crystalline structure and thus have the corresponding high mechanical strength, oxidation resistance and re-melting temperature.
