Abstract

See full text

A turbine blade for the rotor of a gas turbine, having a blade airfoil, which has a blade airfoil main body with a first material and a blade airfoil tip with a second material, the second material being more resistant to oxidation than the first material. The composition of the second material is graduated at least in subregions. A method for producing the turbine blade includes: providing a main body of a turbine blade airfoil on a construction platform of a device for performing an additive method, the main body having a first material; applying a pulverous second material, which is different from the first material, in a certain amount; fusing the pulverous material by applying a high-energy beam; lowering the construction platform, repeating applying and fusing the pulverous material and of lowering the construction platform as many times as necessary to complete the tip of the blade airfoil.
