Beschreibung
Zusammenfassung:	A ridged turbine airfoil (1) for use in turbine engines exposed to high temperatures and a method of manufacturing the ridged turbine airfoil is disclosed. The turbine airfoil (1) comprises an outer wall (2) with an outer surface (3). The outer wall (2) comprises an arrangement (5) of raised ridges (8) having a predefined height (6) located on a region (7) of the outer surface (3) wherein each ridge (8) encloses an area (19) for receiving at least a portion (9) of a TBC layer (4). The TBC layer (4) is to be applied on the outer surface (3). The ridges (8) can be made from a similar material the airfoil (1) is made from to withstand the high temperatures. The area enclosed (19) by the raised ridges (8) enclosing the portion of TBC layer (4) preferably has a hexagonal (20), rectangular (21) or circular (22) shape.
