    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.

    摘要: A method of making a combustion turbine component includes forming a metallic powder including at least one metal and at least one rare-earth element and processing the metallic powder including at least one metal and at least one rare-earth element to form a cohesive metallic mass. A primary aging heat treatment may be performed on the cohesive metallic mass. A homogenization heat treatment may be performed on the cohesive metallic mass prior to the primary aging heat treating. Furthermore, a secondary aging heat treatment may be performed on the cohesive metallic mass after the primary aging heat treating.

    摘要: A method is provided for restoring a near-wall channeled gas turbine engine component (100, 200) which has been exposed to engine operation. In a representative embodiment, a cooling channel (102) of the component (100) is filled with a polymer that solidifies to form a preform material (110) in the cooling channel (102). Then existing outer wall layers (106, 108) of the component (100) are removed, thereby exposing in part the preform material (110). New outer wall layers (106-N, 108-N) are applied over the component (100), and this may be done while a cooling flow is also applied to the component (100). Then the preform material (110) is removed without destroying the new outer wall layers (106-N, 108-N). The new outer wall layers (106-N, 108-N) may be applied by HVOF processes or by other methods.
