Abstract (en)
[origin: WO2011009430A1] Disclosed is a method for hardfacing a metal component surface (14, 16), especially a shroud surface of a turbine blade made of a TiAl alloy, with at least one metal material (18, 20), in particular a Co-Cr alloy. In said method, the hardfacing coating is produced separately from the component surface and is then joined to the component surface in a high-temperature soldering process. Also disclosed is a turbine blade comprising such a hardfacing coating, primarily in a shroud region (2).
