About this file
This document is Addendum 2 to Request for Proposal (RFP) A24-0958 issued by the Ames Laboratory, which is operated by Iowa State University under a prime contract with the U.S. Department of Energy. The addendum modifies, supplements, and replaces information in the original RFP dated 2/22/2024. The key details are:
Item 1 adds Requirement #20 to Appendix C - Specifications, which requests reference data on powder production of refractory elements like tungsten, tantalum, molybdenum, vanadium, and niobium, including powder size distributions, chemical composition analysis, and production/throughput rates. Item 2 extends the proposal due date from 4/00 p.m. CST on 4/1/2024 to 4:00 p.m. CST on 4/15/2024. The addendum also notes that a third addendum will be issued prior to the new due date to lift the draft status of the RFP. The RFP is seeking proposals for a plasma-based metal gas atomization system capable of producing spherical powders suitable for laser-based additive manufacturing from high-melting temperature refractory metal feedstock.

Refractory Metal Atomizer
System Requirements:
1. Plasma-based metal gas atomization system capable of generating spherical powders suitable for laser-based powder-bed additive manufacturing from high-melting temperature (refractory) metal feedstock up-to and including pure tungsten (melting temperatures >3000°C), with a D50 less than or equal to 50 µm and D90 less than or equal to 100 µm.
2. Capable of semi/continuous feeding with processing rates of 1+ kg per hour (not pour rate, indicating average powder production rate) of refractory metal feedstock (ingot feedstock only, no wire).
3. Capable of vacuum levels in the atomization chamber of 1e-4 torr or better.
4. Capable of atomization gas heating to 500°C or higher.
5. Includes water-cooled hearth and atomization chamber.
6. Replaceable Cu melting hearth
7. Maximum system vertical height of 22 feet; preferred footprint is 16 feet by 16 feet
8. Non-explosion rated atomization chamber
9. Pressure relief and burst discs required
10. All tube sections must be shorter than 36 inches
11. Must specify if plasma is transferred or non-transferred arc type
12. Melting chamber must be 30+ inches in diameter
13. Mezzanine or worker access platform must be included
14. Power supplies for gas heating and plasma torch(es)
15. Water interlocks for power supplies must be included
16. Remote/automated control of valves and melt pouring
17. Remote/automated control of plasma torch(es)
18. Please include line item(s) for installation and training time on-site
19. Please include estimated shipping costs
20. Reference data showing powder production of the refractory elements W, Ta, Mo, V, and/or Nb
(or alloys/mixtures of these) including powder size distributions, chemical composition analysis, and production/throughput rates.
