A vane device for a gas turbine having an inner shroud and an outer shroud, an aerofoil arranged between the inner shroud and the outer shroud, the aerofoil and/or inner shroud and/or an outer shroud having a first layer of MCrAlY coating over a substrate, a coated surface section which is coated with a thermal barrier coating over the first layer of MCrAlY coating, a second layer of MCrAlY coating provided between the first layer of MCrAlY and the thermal barrier coating of the coated surface section.

Vane segment for a gas turbine

A vane device for a gas turbine is provided. The vane device includes a first airfoil having a first suction side and a first pressure side, a second airfoil having a second suction side and a second pressure side, an inner shroud and an outer shroud. The first airfoil and the second airfoil are arranged between the inner shroud and the outer shroud, wherein the first airfoil and the second airfoil are at least partially coated with a MCrAlY coating. At least the first suction side has a first coated surface section which is coated with a thermal barrier coating and which represents at least a part of the total surface of the first suction side. At least the inner shroud or the outer shroud has a further coated surface section which is coated with a further thermal barrier coating. A corresponding method of manufacturing is also provided.
