摘要:
A component (1) for a turbomachine and a method for construction thereof: The component includes an inner core (6) and a first thermal bond coating (11) on the inner core (6), and a second thermal bond coating (12) on the first thermal bond coating (11). The first thermal bond coating (11) is sandwiched between the inner core (6) and the second thermal bond coating (12). A second operating temperature (T2max) of the second thermal bond coating (12) is higher than a first operating temperature (T1max) of the first thermal bond coating (11).
摘要:
A turbine blade with aerodynamic aerofoil, which extends from a bottom to a top end and has two aerofoil walls extending between, which transversely thereto extend from a common leading to a common trailing edge, and with at least one platform, which extends transversely in relation to the aerofoil and is arranged at one of the two ends of the aerofoil. A number of openings are provided in the trailing edge between the bottom end and the top end. Either the opening in the trailing edge arranged closest to the platform surface extends into the platform surface or the platform surface facing the aerofoil is lowered locally in the region of that opening that is closest to the platform, and the opening opens out into a portion of the trailing edge that has become free as a result of the lowering.
摘要:
A component for a turbomachine, the component including a coating for minimizing thermal gradients within the component, the coating including a first coating on at least a portion of a surface of the component, wherein the first coating is substantially free from rhenium. Further, the component includes a second coating on the first coating. The second coating includes rhenium for better thermal resistance. Furthermore, the component includes a homogeneous high porosity (HHP) layer on the second coating. Finally, the component includes an abradable layer on the homogeneous high porosity layer.
