    摘要： A method for making a gas turbine component (100). A central core (20) is positioned to occupy a space that will define a central channel (42), and an outer channel core (30) is positioned spaced apart from the central core (20). A mold (35) is formed around the central core (20) and the outer channel core (30), so that an exterior wall (32) contacts the mold (35). A substrate material, such as a metal alloy (247) in liquid form, is added to the mold (35) to form an internal volume (41) of the component (100). The central core (20) and the outer channel core (30) are removed, and interconnect channels (44) are formed between the thus-formed central channel (42) and the inner portion (49) of the outer channel (62) thus far formed. A preform (55) is placed into the inner portion (49) and may have a desired outer surface (57) shape. An overlay material is applied to form an outer layer (60), thus defining the remainder of the outer channel (62), which is obtained upon removal of the preform (55).

    摘要： A method of manufacturing a metallic component includes atomizing, in an inert atmosphere, a metallic liquid having at least one rare-earth element and at least one non rare-earth element to form a metallic powder. A series of heat treating steps are performed on the metallic powder. A first heat treating step is performed in an oxidizing atmosphere, and a second heat treating step is performed in an inert atmosphere. A third heat treating step is performed in a reducing atmosphere to form a metallic power having an increased proportion of rare-earth oxides compared to non rare-earth oxides. The metallic component is formed from the metallic powder having the increased proportion of rare-earth oxides compared to non rare-earth oxides.
