Abstract (en)
The present invention relates to a turbine component (12, 12a) comprising a base body (14, 14a) having at least one cavity (16) providing a flow path (18, 18a) for a cooling medium (20) and at least one wall (22, 22a) at least partially surrounding the at least one cavity (16) and wherein the at least one wall (22, 22a) has an inner surface (24) being oriented towards the at least one cavity (16) and an outer surface (26) being oriented opposed to the inner surface (24) of the at least one wall (22, 22a), wherein the at least one turbine component (12, 12a) further comprises at least one layer (28) of porous material and at least one thermal barrier coating (30), wherein the at least one layer (28) of porous material is arranged on the outer surface (26) of the at least one wall (22, 22a) of the base body (14, 14a) and the thermal barrier coating (30) is arranged at least partially on top of the at least one layer (28) of porous material.Due to this a good cooling efficiency can be provided.
