WEAR-RESISTANT LAYER FOR TIAL

摘要

The invention relates to a wear-resistant part for high-temperature applications made of a TiAl material, in particular a turbine blade comprising an at least double-layered protective coating (4). A first diffusion barrier layer (2) made of a precious metal and a second hard material layer (3) containing hard material particles that are embedded in a precious metal matrix are applied to the TiAl material (1) as a protective coating. The invention also relates to a corresponding production method.
