Much fundamental process research needs to be done on gas atomization to transform this high throughput method for production of metal powders into a precision process for efficient generation of high quality powders that target the needs for AM feedstock powders. Conversion of close-coupled gas atomization to truly “smart” powder manufacturing will require basic process research advances in nozzle design and operating parameter selection and in spray chamber designs. Objectives are to permit control of powder mean size and size range prediction and development of in operando size tuning, as well as powder shape and surface control to enable generation of ideal spherical powder without internal porosity in passivated condition. Progress will be reported on gas atomization process research to mitigate these issues for Ni-based alloy powders, and others, if possible. Supported by USDOE- EERE-Advanced Manufacturing Office through Ames lab contract DE-AC02-07CH11358.
