Abstract (en)
[origin: EP2743455A2] The blade (1) has an erosion protection component (2) provided in the blade. A firmly bonded connection is secured at the blade. A positive connection is fixed with a form closure element (3) by pins or needles, which are engaged with a composite material. A single-piece is formed in the closure element and the erosion protection component. The erosion protection component is formed from a hard metal, titanium or ceramic. An independent claim is also included for a method for manufacturing a turbine blade.
