  • Patent number: 8555500
    Abstract: A method of producing or repairing single-crystalline turbine or engine components by the following steps: heating of braze filler metal to a temperature which is greater than or equal to the melting temperature of the braze filler metal; introducing the molten mass of the braze filler metal produced through the heating process into a crack formed in the turbine or engine component, or into the gap formed between two turbine or engine components, or into a damaged area of a turbine or engine component; and non-isothermal control or regulation of the temperature of the braze filler metal or turbine or engine component during an epitaxic solidification process of the braze filler metal.
    Type: Grant
