  • Publication number: 20210017866
    Abstract: 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.

  • Patent number: 7758309
    Abstract: There is described a vane wheel of a turbine comprising at least one vane, the footing thereof being held on a wheel disk. At least one cooling channel is arranged between the wheel disk and the vane footing. The vane wheel having a plurality of turbulators is embodied on at least one of the walls of the cooling channel, the turbulators being configured in such a way that the turbulence and thus the heat transfer of a cooling fluid flowing through the cooling channel are increased.
