Embodiment Construction

[0035]The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

[0036]Referring initially to the flowchart 14 of FIG. 1, a first embodiment of a method of making a combustion turbine component is now described. After the start (Block 15), at Block 16 a plurality of metallic combustion turbine subcomponent greenbodies are assembled together to form a metallic greenbody assembly. The metallic greenbody assembly has a shape closely resembling that of the final combustion turbine component, but has a greater porosity, a le...

Abstract

A method of making a combustion turbine component includes assembling a plurality of metallic combustion turbine subcomponent greenbodies together to form a metallic greenbody assembly and sintering the metallic greenbody assembly to thereby form the combustion turbine component. Each of the plurality of metallic combustion turbine subcomponent greenbodies may be formed by direct metal fabrication (DMF). In addition, each of plurality of metallic combustion turbine subcomponent greenbodies may include an activatable binder and the activatable binder may be activated prior to sintering.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of the filing date of U.S. Provisional Patent, Ser. No. 61 / 022,952, filed on Jan. 23, 2008.GOVERNMENT CONTRACT[0002]The U.S. Government has a paid-up license in this invention and the right in limited circumstances to require the patent owner to license others on reasonable terms as provided for by the terms of contract No. DE-FC26-05NT42644 awarded by the Department of Energy.FIELD OF THE INVENTION[0003]The present invention relates to the field of metallurgy, and, more particularly, to methods of making a combustion turbine component from a plurality of metallic combustion turbine subcomponent greenbodies.BACKGROUND OF THE INVENTION[0004]A combustion turbine typically includes, in a serial flow relationship, a compressor section to compress the entering airflow, a combustion section in which a mixture of fuel and the compressed air is burned to generate a propulsive gas flow, and a turbine section tha...
