Project Description

Edison Welding Institute will develop a novel process to qualify the additive manufacturing (AM) technique of laser powder bed fusion (L-PBF) for complex gas turbine components made of high temperature nickel-based alloys. The project objectives include evaluating the impact of (1) powder selection method, (2) AM machine process parameters, and (3) heat treat sensitivity on the manufacture of production-scale fuel injector tips.

Project Benefits

This project will also provide information that will assist in determining if other turbine components are candidates for AM fabrication. The AM flexibility will allow industrial gas turbine manufacturers to design features into the components that may improve turbine performance and durability. Other benefits include reduction in manufacturing time, scrap material elimination, development of an additive manufacturing process that can improve both material and mechanical properties with little to no impact on durability compared to the traditional investment cast process.
